Peeked at the source of both and they seem to have certain functionalities scripted to the same button press.
Using them both at once will likely cause unintended behaviours, so no point.
You shouldn't expect two different mods to work together, especially if you're not willing to learn Lua to try and mess with both source codes.
It's not like someone making a mod will be bothered to take into account every other existing mod.
Still, if you want to try, just take both mods' STimeCycle.lur, rename them to whatever, and then load both in your STimeCycle script, to see what happens.
You use this function to launch a .lur script. (Provided it's either in the Scripts folder or in Scripts.img)
LaunchScript("NAMEOFSCRIPT.lua")
