How do I get a UTC Timestamp from Calendar?

Question

In Java when I use Calendar.getInstance(); I get a Calendar object for the current Timezone. But java.sql.Timestamp is usually stored in U

Answer 1

Your code is already doing exactly what you want. Timestamp (as well as Date) does not have timezone information and should always contain a GMT timestamp (which ist what Calendar.getTimeInMillis() returns).

The reson why you see local time printed is that the DateFormat factory methods as well as Timestamp.toString() implicitly use the system timezone.
