I will touch on this on going problem as well. My time zone has repeatedly changed on its own. There use to be an option in each members profile to set individual time zones, it has since disappeared. And with the daylight savings time change, my time is now 2 hours off. This is becoming a real headache trying to plan out and schedule events, I have members showing up early,late, and on time. This bug needs to be addressed ASAP.
