Sorry Jan I disagree with this:
Dios's pyramid is the only one that runs time backwards (as seen when the torch the King and Gern take in un-burns itself) I think he effectively subtracts each day after he has lived it - the mummies pyramids don't or they would'nt come out of them with the older ones looking more worn and with bandages falling off.
Also wouldn't you expect the flare off of time from all the Pyramids to accelerate time in the rest of the valley not slow it? (Trying to think logically about it)
No - they're all the same except in physical dimensions. Dios doesn't die but then he doesn't age or get younger either does he? So he's also marking time exactly like the dead kings, never getting older or younger so his pyramid performs the same function as the others - the pyramids simply preserve time and their 'inmates' never change. As the pyramids also 'leak' into the outside world this does slow time down in the rest of Djelibeybi and makes any significant change impossible especially as Dios is there to keep things going on the same way by building more and more pyramids.
The kings do die and are mummified, so their spirits live on in that inanimate state, whilst their pyramids are working properly. If they're mummies that's how they stay and never leave their tombs. Dios is alive of course and he stays that way and can come and go as he pleases, but as he goes on he wants/needs to use the pyramid more and more, but becomes tired and careless. Taking that point further of him being pyramid-dependant, he keeps having the kings build bigger and bigger pyramids and so Teppic's dad's one is the final straw (that broke the camel's back )and sets the whole lot of them off in the Star Trek sense that 'the pyramid cannae take it!'

The time that should have passed in the chamber was stored in the bulk of the pyramid and allowed to flare off once every twenty-four hours.
