In my case the EPG display the entries 2 hours too early.

FWIW, my system handled the change without problem, so it's not a universal issue.

Is the problem to do with how you have EPG times defined, perhaps? Configuration -> DVB Inputs -> Networks -> Edit... EIT local time?

This is not checked. I not use over the epg. Before the summertime change epg is working exactly. But after this change epg is worng 1 hour. I automaticly created xmltv file on my server with php. And program date is example: programme start="20150401020000 +0200" stop="20150401043000 +0200" so this is 02:00 start and 04:30 finish. My system(Openelec) time is 02:00 but epg says program start 03:00. So 1 hour different here. I trying solve this problem 2 days but i cant find anything. I try to change epg source date -1 hour.

Here is the routine which parses the time string:

TVH uses UTC internally. Note that we set tm_isdst to -1 which may apply another correction to the parsed time.

I clicked on Configuration -> DVB Inputs -> Networks -> Edit... EIT local time and have the check mark set.
Now I have one hour difference.
Why is there anyway this option? Could this be removed to limited the complexity a bit?

Sorry wrong statement above. It is still 2 hour ahead!

I unchecked this EIT check mark and had the EPG reloaded. I seems to be correct now!

Same problem here. After change to german summertime all epg is 2 hours back, enabled eit local time but nothing changes.

OK, sorry, problem seems gone by disabling the eit checkmark....seems it needs some time to update epg data. My system runs with local time, so maybe the checkbox did not do what it should do.
