When is the next day?

In hearthstone, you receive one quest per day, barring unique quests. What I'm wondering is when exactly does a new day start? I assume it's at a specific global time, so I'm looking for a time in GMT or UTC.

I did find out you need to exit the game and come back to receive new quests, but I'm hoping someone actually knows when i have to do that.

Solution 1:

Daily quests are reset at 3 AM server time, which will differ based on your currently set Battle.net region, and which specific server you connect to: the numbers below may vary.

• For the North American region, servers are typically on PST (-7 GMT), which means that currently (as the US is in daylight savings time) it will reset at 10 AM GMT.
• For the European region, servers are typically on CET (+1 GMT), which means that they will reset at 2 AM GMT.
• For the Asian region, servers are typically on KST (+9 GMT), which means that they will reset at 6 PM GMT.
