holiday calendar only supports timezone GMT+01:00

[ddelange]

It seems that the only timezone in the holiday calendar of the job scheduler that works is GMT+01:00 or Europe/Amsterdam, which is the same, other timezones have no effect on the scheduler. 

Does anybody know if I'm doing something wrong or that there are other timezones that do work? I have tried GMT+08:00 orAsia/Singapore, GMT or Europe/London but they don't work either.

Below is an example of the contents of a holiday calendar

Kind regards
