On web version you can set timezone by yourself. If you move to somewhere the time zone is changed, you can only set the timezone on your device, because of doit.im can't identify the timezone. Sorry for the inconvenience brought to you.
Linjiani, this is a big problem, whenever the time zone is changed all scheduled tasks move one day !!
the problem is not set the time zone, I do it manually, the problem is that scheduled tasks are changed daily. I can not trust my programming after changing the zone.
This happend when mi phone change of time zone first that the APP.
@Linjiani again this problem :( I'm finding another app because this is a big problem for me, on all my travels I need move one day ahead all my task!!!
Thank you for your feedback!
