Hello all, i am completely new to this and i am really sloppy.

Can i know which timezone is gonna be used?

for example:

the new day for Razer Cortex starts at my midnight or on 1 am? or even 3 am?

Also i got another question even if prolly i know the answer already: If i redeem the 20 hours prize, am i going to lose the 20 hours?

Thanks to whoever answers!
