Question

I am trying to get the current offset between NY(US/Eastern) and UTC. How can I get this value regardless of what timezone my server is in, and anything else. I just want the offset in milliseconds. I am sure there is a quick way to do this, but I haven’t found it.

Thank you in advance!

Note: this is not tested.

Using:

Calendar class

TimeZone class

//Get NY time zone instance
TimeZone ny_tz = TimeZone.getTimeZone("America/New_York");

//Get NY calendar object with current date/time
Calendar ny_cal = Calendar.getInstance(ny_tz);

//Get offset from UTC, accounting for DST
int ny_offset_ms = ny_cal.get(Calendar.ZONE_OFFSET) + ny_cal.get(Calendar.DST_OFFSET);
