Where did you put your search engine? :-) – Ole V.V. Aug 07 '22 at 08:39

If you meant Central time zone, you can’t without a date. You need to know whether it’s in the standard time or the summer time (DST) of the year. – Ole V.V. Aug 07 '22 at 08:41

You of course also need to know the source time zone. – Ole V.V. Aug 07 '22 at 09:06

Which to use?
For time zone, avoid both Date and Calendar If you are using JDK >= 8, use the new java.time.* framework. If you are using JDK < 8, use Joda Time. (The new Java 8 java.time.* framework is inspired by this library)
Applying date command
The java.util.Date has no concept of time zone, and only represents the number of seconds passed since the Unix epoch time – 1970-01-01T00:00:00Z. But, if you print the Date object directly, the Date object will be always printed with the default system time zone. Check the Date.toString() source code.
Set a time zone to DateFormat and format the java.util.Date
