Tresclub:
If it is 10an PDT on my computer. what time is it on the WGT server?
There are a couple answers to that question.
The official time for WGT-sponsored tournaments, Clashes, forum post timestamps, and most other times that WGT uses is PDT (since WGT headquarters is located in California).
The official time for the start of the new day (to continue your Consecutive Days Played or CDP) is midnight UTC. PDT is 7 hours behind UTC.
Hope this helps.
