i figured it out!
label start:
$ phone.system.battery_level = "77" >this is for the battery level<
$ phone.system.date = datetime.datetime(year=2025, day=17, month=2, hour=5, minute=43) >and this is for the custom time and date<
in another rpy file, add this:
init python:
import datetime
>this is because datetime is not added by default<
