It is run once at system startup after app_server and co are running.
Its job is to make sure the system clock took daily saving time into account.
To do this, it compares DST from a config file with DST from current RTC info.
If they differ, a time-updated alert is showed to let the user choose what to do.
A system call was used on R5 to get the current RTC info.
Unless someone comes with a good reason to still use a syscall, it should stay as is.
