Extract
In the past, the unpredictability of IDT in Israel became frustrating enough that Microsoft Windows stopped trying to track changes and just made Israeli time be Greenwich Mean Time plus two hours (GMT+2) (and disabled the daylight saving option). This led to various ad hoc solutions to the problem in Windows systems and other Microsoft software (e.g. Outlook calendar entries were often off by an hour when shared, due to the lack of IDT support).
