How is time set for bulbs/plugs?

I’ve got several Wyze bulbs and outlets in my house, which is on US PDT time. I’m currently in France, and the bulbs have picked up my french timezone, so the timings were all messed up. Have had to reset them to the equivalent French time. Of course when I go back home I’ll have to do the same thing all over again.

There’s no “set time” function for bulbs/plugs, the way there is for the cams. Anyone know what actions cause the bulbs/plugs to update the time? If it’s just certain actions like adding a new timer then I can change my phone to Seattle time before I do those things, but if it resets it every time I access a bulb (e.g. to turn it or view details) then that would be a hassle. Any (useful) suggestions appreciated!
