ITC-306T wrong time

the time of my ITC-306T controller is always wrong. I can set it correctly, but within some hours the time is completely wrong again.
Example: I set the time correct at 11am. When I checked the time at 7pm, the time of the ITC-306T controller was 2pm.
Because of the wrong time it’s impossible to use the ITC-306T controller to turn on/ off the heating lamp of my terrarium.
Is there a way to fix this or is the ITC-306T controller broken?
I bought the ITC-306T in December 2016, so there’s no warranty anymore.
Thanks and regards,

It’s probably a problem with the internal time chip, it can’t be fixed, sorry.

Hello Tania,
I was afraid someone’s providing this kind of feedback :sob:
Many thanks anyway.
