Tvheadend

Hello,

I have 2 different networks in my Tvheadend, one is DVB-S2 and I use an external XMLTV grabber, it works well.
The other network is DVB-T channels and I get EPG data over EIT "over-the-air". The problem is that EIT data has 2 hours offset.

How could I fix it? Could I configure it somewhere?

Thanks for your help.

Kind regards.
