Thanks for the reply, i would like an "official" confirmation from @Bram Hengeveld if possible pleaseNo it is correct, Greece is GMT+3 and as UK is on summertime now (as most of Europe) they are on BST which is GMT+1.
Edit: So yes, you are on BST+2 but RD will always use GMT as that time is a constant sts
Edit2: BST = British Summer Time
