Date.UTC()

The Date.UTC() method accepts the same parameters as the longest form of the constructor, and returns the number of milliseconds in a Date object since January 1, 1970, 00:00:00, universal time.

Syntax

Date.UTC(year, month[, day[, hour[, minute[, second[, millisecond]]]]])

Parameters

year

A year after 1900.

month

An integer between 0 and 11 representing the month.

day

Optional. An integer between 1 and 31 representing the day of the month.

hour

Optional. An integer between 0 and 23 representing the hours.

minute

Optional. An integer between 0 and 59 representing the minutes.

second

Optional. An integer between 0 and 59 representing the seconds.

millisecond

Optional. An integer between 0 and 999 representing the milliseconds.

Return value

A number representing the number of milliseconds in the given Date object since January 1, 1970, 00:00:00, universal time.

Description

UTC() takes comma-delimited date parameters and returns the number of milliseconds between January 1, 1970, 00:00:00, universal time and the time you specified.

You should specify a full year for the year; for example, 1998. If a year between 0 and 99 is specified, the method converts the year to a year in the 20th century (1900 + year); for example, if you specify 95, the year 1995 is used.

The UTC() method differs from the Date constructor in two ways.

• Date.UTC() uses universal time instead of the local time.
• Date.UTC() returns a time value as a number instead of creating a Date object.

If a parameter you specify is outside of the expected range, the UTC() method updates the other parameters to allow for your number. For example, if you use 15 for month, the year will be incremented by 1 (year + 1), and 3 will be used for the month.

Because UTC() is a static method of Date, you always use it as Date.UTC(), rather than as a method of a Date object you created.

Examples

Using Date.UTC()

The following statement creates a Date object using UTC instead of local time:

var utcDate = new Date(Date.UTC(96, 11, 1, 0, 0, 0));
