When is the best time to call London from Jakarta?

Between 15:00–18:00 in Jakarta, which is 09:00–12:00 in London. That is the only stretch where both cities are inside a 09:00–18:00 day.

Does Jakarta observe daylight saving time?

No. Jakarta stays on UTC+7 all year, so its clocks never move.

If it is midday in Jakarta, what time is it in London?

It is 06:00 in London, on the same calendar date. That holds for the current offsets; it shifts by an hour around the daylight saving dates listed above.

Which time zones do Jakarta and London use?

Jakarta uses Asia/Jakarta, currently UTC+7, and London uses Europe/London, currently UTC+1 (BST). Those identifiers are the ones to use in code — abbreviations are ambiguous and offsets change.
