The following four weeks will mean a period of total time confusion in SecondLife before Europe and Australia catch up.
Europe "springs forward" on Sunday March 29, 2015, while Australia (in the southern hemisphere) "fall back" on Sunday April 5, 2015.
...and then all will be well for awhile until the fall, when we go trough the opposite confusion.
Bock in SecondLife is - as always - here to aid you and has a clock with the correct SLT time in the right column for your convenience.
UPDATE: Edited according to my friend Petr's correct observation in his comment below!
