24 minutes to 1 day

I need help if this is possible. So, we know 20 minutes is 1 day in Minecraft so, my question is, is there any way I can slow down the time to make it 24 minutes is 1 day in Minecraft or even slower? I'm doing this on MCPE, btw

Sadly there are only options to freeze or to set time in any version of the game, you could however set a redstone clock, that every once in awhile freezes time for some time, something like freezing for 1 minute, every 5 minutes, which would grant you your wanted result.

If such a clock is running in the spawn chunks your problem should be solved (at least that is how i would try to address it in Java. Don't know if that is applicable in pocket-edition, since redstone is not really reliable in that edition as I heard).
