Evening. New to the forums so if this has already been posted my apologies.

Every other day or so, the clock on my phone changes time by itself for some reason. I have the timezone set to GMT - 5 for Easter US (I'm in Ontario, CAN) and also have the enable local time and use network time zone settings checked off. I can't figure out why this is happening? Please help! Cheers!

p.s. When I power off the phone and power it back on, the time resets itself properly, however it will eventually change again in a day or so.
