Welcome to the Forum, @nickmonaghan! 
Maybe take a look at this topic:
I think Wyze has a history of some of their devices not handling time-based features very well, and this may be one of those cases.
That shouldn’t matter if you’re using sunset/sunrise-based schedules. That’s used only if you want to use ambient light to control the sockets, at least as I understand it. If you’re using both the Schedules and Brightness features with your Plug Outdoor, then I guess there could be some kind of conflict, but if this behavior is also affecting a regular Plug in the same way, then I’m guessing it’s a time offset issue similar to what was described with Lamp Socket v2 in the topic I linked above.
If you’ve confirmed that your phone’s time is correct as @R.Good suggested (and you can also try giving the app your location at Account ➜ Home; I would expect the app to use this information to determine sunrise/sunset times at your location, but I’m not convinced that Wyze is actually using this data that way), then you can add a 1-hour offset to your schedule as a work-around, but I’d also consider submitting a log if you haven’t already done that.
What did Support say when you contacted them?

One other thought: If you’re using Local Schedules on the plugs (present on Plug Outdoor and later generations of Plug; original Plug v1 does not have Local Schedules), then you could try creating Schedule Automations instead and see if that makes a difference in your experience…or vice versa.
