JavaScript Date.UTC()

The Date.UTC () method in JavaScript returns time based on the date of January 1, 1970 and the time of 00.00.00.

Years between 0 and 99 are converted to a year in the 20th century (1900 + year); for example, 95 is converted to the year 1995. UTC time is the same as GMT time.

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.

Syntax:

Date.UTC(year, month, day, hours, minutes, seconds, millisec)
