There seems to be an issue with the clock and timezones. I did some 1 hour in China today and when landing in Sweden i changed to Swedish timezone. The clock is counting up but when i leave the study page and then go back again the clock goes back to approximately 63 minutes all the time. I did a couple of 10 minute sessions but all the time i where back on 63 minutes when i did go back to the study page. Is there any caching involved here? When i changed the timezone it where a new day in China so the counter had started over for a new day when i changed back to Swedish time.
