Not in all cases. You may have noticed already, but casino time is often not the same as your local time.
A lot of casinos set their time zones on UTC, or use this time for the start and end of deals. UTC is the standard world time, also referred to as Zulu time. Thanks to UTC time, players all around the world can play at online casinos. Most international websites on the internet use UTC. UTC is practically the same as Greenwich Mean Time (GMT). At some casinos, you can change the time zone at your profile settings.
