Using the Windows client on my Windows 7 Pro notebook, I regularly get the message

"The timezone in Doit.im is inconsistent with that in your device. Doit.im timezone: (GMT +9:30) Adelaide. Device timezone: (UTC +9:30) Adelaide. Please go to Preferences in Doit.im for web to reset the timezone."

But the Preferences do not have the option of UTC zones.

Doit.im should recognise UTC = GMT?
