Microsoft® JScript™ UTC Method |
Language Reference Version 1 |
Computes the number of milliseconds between midnight, January 1, 1970 Universal Coordinated Time (UTC) (or GMT) and the supplied date.
Date.UTC(year, month, day[, hours[, minutes[, seconds[,ms]]]])The UTC method syntax has these parts:
Part Description year Required. The full year, for example, 1976 (and not 76). month Required. The month as an integer between 0 and 11 (January to December). date Required. The date as an integer between 1 and 31. hours Optional. Must be supplied if minutes is supplied. An integer from 0 to 23 (midnight to 11pm) that specifies the hour. minutes Optional. Must be supplied if seconds is supplied. An integer from 0 to 59 that specifies the minutes. seconds Optional. Must be supplied if milliseconds is supplied. An integer from 0 to 59 that specifies the seconds. ms Optional. An integer from 0 to 999 that specifies the milliseconds.
The UTC method returns the number of milliseconds between midnight, January 1, 1970 UTC and the supplied date. This return value can be used in the setTime method and in the Date object constructor. If the value of an argument is greater than its range or is a negative number, other stored values are modified accordingly. For example, if you specify 150 seconds, JScript redefines that number as two minutes and 30 seconds.
The difference between the UTC method and the Date object constructor that accepts a date is that the UTC method assumes UTC, and the Date object constructor assumes local time.
The UTC method is a static method. A Date object does not have to be created before it can be used.
Note If year is between 0 and 99, use 1900 + year for the year.
