In .Net UTC and GMT are not the same Difference between UTC and GMT Standard Time in .NET
Is it the same with Java? Does Java has the notion that GMT has DST changes while UTC doesnt?
Thanks!

Daylight Saving Time and GMT is different. GMT is GMT, wherever and whenever.
GMT+0 is standard British Time
GMT+1 is BST (British Summer Time)

As the documentation explains, GMT is equivalent to UT and the difference between UT and UTC is "is an invisibly fine hair to split". As Codemwnci explained, GMT will never have DST applied to it.
GMT and UTC will never have "Daylight Savings" or "Summer Time" applied to them.

You're misreading the other question. It's not "UTC vs. GMT", it's "UTC vs. GMT Standard Time".
