Answer 1

Use Calendar#getTimeInMillis:

Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long time = cal.getTimeInMillis();

That is the most complicated and inefficient way of getting the GMT time I have seen. :D Under all this it has to call System.currentTimeMillis() which returns the time in millis for GMT. – Wanyen

@PeterLawrey: Why do you assume OP always wants the current time? – Facesaving

That is true, but if you need to store the GMT time in millis, you can use long for that too. – Wanyen

Will it also handle daylight saving correctly? – Sofer

Answer 2

You can use System.currentTimeMillis() it returns "the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC."

long time = System.currentTimeMillis();

Will do it :)

Doesn't that use the system time rather than just using GMT? If so, wouldn't this cause problems if you need the milliseconds to be standardized across more than one time zone? – Jurisdiction

This returns the exact same result as the accepted answer, but is much more concise. – Thought

Answer 3

Use the Calendar Class to create an instance with GMT as the timezone.

From that you can get the time in milliseconds.

see below code sample.

public class TimeTest {

    public static void main(String [] args) {
        Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
        System.out.println(cal.currentTimeMillis());

    }
}

Hope this helps.

For current time in millis always prefer System.currentTimeMillis() and also if you are using Calendar prefer cal.getTimeInMillis() instead of cal.getTime().getTime() – Carmellacarmelle

Answer 4

Use getTime() function:

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.
