Apex Time/clock drift

[IvanW]

Over the past several months I have noticed that several time settings have drifted. My auto feeder was originally set for 12 noon and 9pm. The time has now moved about 20/25 minutes. I have also just noticed this on my refugium light.
I don’t know if this has been discussed anywhere else as I have not found it in any of my searches, I have not really spent too much time on it. Anyone having this issue and if so how do I fix it?

Do you have your Apex clock configured to Auto Clock Set? This forces it to frequently synchronize the clock over the Internet, keeping it accurate. If this is not enabled, it could explain why yours is drifting.

Yes it is enabled

Purely speculative guessing here, is the device you are using also on auto set time?
