Best overlap: 8:00 AM to 12:00 PM in London is 2:00 PM to 6:00 PM in Jakarta.
Both offices are open during 8:00 AM to 12:00 PM London time, which is 2:00 PM to 6:00 PM in Jakarta. You've got a decent 4-hour window. Set a recurring time near 8:00 AM in London (2:00 PM in Jakarta) and stick to it. Heads up: because London changes its clocks and Jakarta doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
