Does daylight saving change WIB to GMT?
Western Indonesia Time does not move its clocks at all, so its UTC+7 offset holds every day of the year.
Greenwich Mean Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
Is WIB ahead of or behind GMT?
WIB is ahead of GMT by 7 hours: when it is 12:00 pm in Jakarta, it is 5:00 am in GMT. Neither Western Indonesia Time nor Greenwich Mean Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Western Indonesia Time covers Jakarta, Bandung and Medan, the most populous of the three Indonesian zones. Greenwich Mean Time covers identical to UTC as a clock reading, and a separate thing as a standard. The identifiers behind them are Asia/Jakarta and Etc/GMT, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
