Please remember that September 16 at 2:00 (tonight) the daylight saving time ends in Israel and we move to the standard time which is one hour back: the time will be 1:00. A special attention is required during time switching otherwise your EPG might be one hour shifted. MegaEPG takes the timezone and DST flag from the operating system. You have to turn the DST flag off in the system time Time Zone properties (or verify it's off and the time is correct).
If you are using Microsoft Vista, you should download a patch that corrects fixed dates for Jerusalem timezone. I'd also recommend all Windows users to switch the internet time synchronization off for about a week untill all the time servers recognize Israel standard time.
Please ensure that your EPG is correct tomorrow! Even if your timezone and the system clock are ok, providers may forget to change the time offset and you'll see a shift. Let me know if any script provides wrong times!
