Danfoss 715 timer

[bright spark]

Hi I have a customer with 1 one of these timeclocks for two zones heating and hot water. Setting program is not a problem but the clock is auto set for time and date. The clock is a couple of years old now and is running half an hour slow.
is there any way of changing the actual time setting.

Thanks Steve it says there that it's factory set. I'll read some more thanks

They are factory set, but I find they are a few minutes wrong out of the box.
I had to fit a replacement identical model recently and had to read how to set it.
Not very logical the new Danfoss FP 715
