The given times for closing bets are either wrong, not adapting to the time zone selected or simply missing the info which time zone they refer to.
For example (copied from liquibets):
Proleague
2015 SPL Round 4 Week 3 Match 2
Betting closes: August 03 2015 20:30
Proleague
2015 SPL Round 4 Week 3 Match 1
Betting closes: August 03 2015 18:30
Both are already closed even so it's not yet 18:30 cest (that's my set time zone for TL)
I've just missed those two bets because I thought I still had plenty of time
