How to set the daily time as the time of a certain time zone, thank you

[hopy11]

every 1.day, at: '3:00' do
  runner "MyModel.nightly_archive_job"
   end

The 3:00 above is UTC time, right? What if I want to set 3:00 every day in Beijing, China time zone? How can I write time expressions? I wrote "at: '3:00 +0800'" like this, but it didn't work.

Thanks ;)

@hopy11 If you haven't, take a look at https://github.com/javan/whenever/issues/826

Unfortunately due to DST and other weirdness there's a lot more that goes into this than simply specifying the timezone :(
