For convenience, there are builds available on momentjs. If you use one of the above files, you still need moment. When using Moment Timezone in the browser, you will need to load the data as well as the library. You can either use the prebuilt library and data files linked on the homepage or build a subset of the data yourself and load it. It takes all the same arguments as the moment constructor, but uses the last argument as a time zone identifier:. Note that created moments have different UTC time because these moments were created in different time zones.
In this example, you first create moment " " object in your default timezone, and then change its timezone to specified. Note that created moments have equal UTC time because these moments were created in a default timezone. The moment. The offset is only taken into consideration when constructing with an array, string without offset, or object.
If the input string contains an offset, it is used instead for parsing. The parsed moment is then converted to the target zone. Unix timestamps and Date objects refer to specific points in time, thus it doesn't make sense to use the time zone offset when constructing.
Using moment. Strict parsing requires that the format and input match exactly, including delimeters. Due to daylight saving time, there is a possibility that a time either does not exist, or has existed twice. In the spring, at the start of DST, clocks move forward an hour. In reality though, it is not time that is moving, it is the offset moving.
Moving the offset forward gives the illusion that an hour has disappeared. As the clock ticks, you can see it move from to to It is easier to see what is actually happening when you include the offset. The result is that any time between and never actually happened. Moment Timezone accounts for this.
Moment Timezone Documentation
If you try to parse a time that never existed, it will skip forward by the amount of the DST gap usually 1 hour. In this example, the two o'clock hour doesn't exist, so it is treated as equivalent to the three o'clock hour. In the fall, at the end of DST, clocks move backward an hour. Again, time is not moving backwards, only the offset is.

I'm trying to convert UTC time to the local time. I can't seem to get the right local output. For example, if its 30 am in here, instead of getting ill get Here is my code:.
No matter what I do the time always comes out at UTC time. I live in Houston so I know timezone is the issue. I've followed the code in the link but can seem to get the local time. What am I doing wrong?

Also, found it makes life easier if you always save things in utc then format on the client side. This worked in my case where we are saving the time in UTC in our db and only displaying local time on the client.

The offset is set on the moment object that utcOffset is called on. If you are wanting to set the offset globally, try using moment-timezone. Note that once you set an offset, it's fixed and won't change on its own i. If the input is less than 16 and greater thanit will interpret your input as hours instead. The utcOffset function has an optional second parameter which accepts a boolean value indicating whether to keep the existing time of day.
Passing false the default will keep the same instant in Universal Time, but the local time will change. Passing true will keep the same local time, but at the expense of choosing a different point in Universal Time. One use of this feature is if you want to construct a moment with a specific time zone offset using only numeric input values:. From here you can search these documents.

Here is what I am doing:. This is found in the documentation.
With a library like moment, I urge you to read the entirety of the documentation. It's really important. You're only setting your input to utc time, it's as if your mentioning that myTime is in UTC, Read this documentation of moment. With that you have the expiring date in UTC. Now you can get the "right-now" date in UTC and compare:. Learn more. Convert date to UTC using moment. Asked 5 years, 11 months ago. Active 4 months ago. Viewed k times.

That only changes the methods used on the date, not the date itself. Colleen - yes, but one would usually then call one of those methods, such as. It can't change the internal date value itself, because a Date is already tracking a UTC timestamp.
It's always just the methods called on it that determines whether to emit UTC or local time. Moment is the same in that regard. I use this method and works. ValueOf not works to me.

Check out this scrimba moment guide if you're just starting. The moment object in Moment. This means that operations like add, subtract, or set change the original moment object. When first using Moment. As you can see, adding one week mutated a. To avoid situations like that, clone the moment before performing date math:.
In Moment. Date math does not use a linear time scale, but rather increments or decrements the dates on the calendar. This is because the amount of time in a day, month, or year is variable.
For example, due to daylight saving time transition, a day may be anywhere between 23 and 25 hours long. Months of course vary in number of days, and due to leap year, years vary in length as well. Date math can cause some interesting scenarios. Because of the variability of duration in day math, Moment's API does not officially support adding or subtracting decimal values for days and larger.
As of 2. This means that 1. It is expressed in the format HH:mm most of the time. A time zone usually has more than one offset from UTC due to daylight saving time. Several time zones may have the same offset at some point during the year. For this reason, it is impossible to infer a time zone from just an offset value. The Moment. It does not provide support for adjusting dates based on time zone data - this is provided by the Moment TimeZone library. For an in depth description of this issue, see the Stack Overflow tag.
In doing this, Moment. Parsing is notably unpredictable with native date. There is no good work-around for this behavior with the native Date object. Moment's parser handles it just fine though:. Effectively what this means is that ISO dates without an offset are to be treated as UTC values, creating the following oddity:. The ES spec fixes this mistake, bringing it in line with the ISO specification, which specifies local time absent of offset.
This is in it's own way bad as it has numerous negative back compatibility implications. With Moment, the date is always interpreted as local time, unless you specify otherwise. This is not something that will change with the adoption of ES Arithmetic is another area where the native Date object is lacking. The Date object actually provides no API for this.
Instead, it relies on overflowing date values.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Have a question about this project?

I don't know of anything in the spec specifying that date strings are expected to be in UTC. From Wikipedia's entry on ISO :. If no UTC relation information is given with a time representation, the time is assumed to be in local time. That doesn't actually say what time a date should be interpreted as dates, as far as is concerned, are just dates, not a specific number of millisecondsbut given that we are translating a date to a time, it seems reasonable to follow the time rules, where everything is local unless specified otherwise.
So I believe the behavior you see is correct. I don't have a copy of the spec and I'm certainly no expert on it. Alternatively, can also use 'Z' the input string to make it parse it as a UTC time, like moment 'Z'. I'm not sure if that's spec or not, but it's consistent with the spec's rule about 'Z' meaning UTC on times e.
Note that until you specify otherwise, the moment will still express that parsed-as-UTC time as the equivalent local time:. ECMA says the following at All numbers must be base If the MM or DD fields are absent 01 is used as the value.
If the HH, mm, or ss fields are absent 00 is used as the value and the value of an absent sss field is The value of an absent time zone offset is Z. I guess a date-only string without time zone follow this rule, and some modern browsers Chrome, Firefox look doing so.
There is a bit of a mismatch because ISO implies that any time that doesn't have a Z or an offset like is to be treated as local time. However, I don't think it would be a good idea to have moment follow this convention.All code should work in both of these environments, and all unit tests are run in both of these environments.
Note: In 2. It will be removed in next major release. Notable files are moment. We strongly recommend reading this if you plan to use moment with Require.
Also upgrade to 2. Then you should use a tool like adapt-pkg-mainor manually -- using packages config. For more complicated use cases please read excellent explanation by jrburke. Moment will still create a moment global, which is useful to plugins and other third-party code. If you wish to squash that global, use the noGlobal option on the module config. If you don't specify noGlobal then the globally exported moment will print a deprecation warning.
From next major release you'll have to export it yourself if you want that behavior. For version 2. Note: To allow moment. Because of this, moment must be loaded exactly as as "moment"using paths to determine the directory. Note: From version 2. Note: There is a bug that prevents moment. Note: By default, webpack bundles all Moment. To strip unnecessary locales and bundle only the used ones, add moment-locales-webpack-plugin :.
