Ok so earlier today my account ran out of time, normal thing. However it kept on giving me a countdown of "How much time" was left. So when it said "28 Minutes of Gametime" left. I tried to do my dailys in a hurry. When the time reached "10 Minutes of Gametime" left, I logged onto my bank alt to check some auctions. Funny thing was, when I logged onto him, The timer reset back to 28 minutes. In Short:
1. Have your Gametime (My use of time was a Gamecard) expire.
2. log onto an alt
3. Time Resets.
I got an extra 5 hours of playtime after the time ran out. I could even log on after the time did infact run out. Ill add screen shots the next chance I get.
