Ability to backdate Utility data entries.

[DarkFoxDK]

My heating and water company offers an online portal for seeing water and heating usage, unfortunately, there's a delay of ~48 hours (and a resolution of one whole day).

I've got a script working that fetches the two day old data every night at midnight, when it becomes available. But due to the delay, it ends up on the wrong day in Domoticz.

It'd be really nice, if there was a way to specify a different timestamp for the entry.
