Alright motherfuckers, if this goes on any longer I'm gonna pop an aneurysm or something.
TL:DR, stop being pedantic.
Not summer time:
CET (Central European Time, used by countries such as Sweden, Germany et cetera) = 18:00
EET (Eastern European Time, used by Finland amongst others) = 19:00 (CET + 1, see that fuckin' plus?)
Summer time... lord help me:
CEST (Central European Summer Time, swedes use this currently) = 19:00
EEST (Eastern European Summer Time, finns use this currently) = 20:00
... you see a pattern here bitches? +1 plus one whatever Sweden is.
All of this means that finland is just +1 from your lovely neighbours, so for all intents and purposes cet = cest and eet = eest unless you're the most pedantic fuck alive and you swill around some port in your mansion while reading some random ass broadsheet.
Hell, if you even look up "Finland timezone" on google, guess what you get? https://www.google.co.uk/search?q=finland+timezone&rlz=1C1ASRW_enGB737GB737&oq=finland+timezone&aqs=chrome.0.0l6.2418j0j7&sourceid=chrome&ie=UTF-8
Fucking Eastern European Timezone.
Cut the shit, cut the S, in practice it means a same thing unless you have to use a calculator to subtract 1 hour from a clock face because mathematics is too damn difficult, in which case, what the fuck.

Edit: Ffs in summer we (UK) go to BST instead of GMT, guess what though? We still call it GMT since EVERY COUNTRY IN EUROPE SYNCS UP WITH THE CLOCKS GOING FORWARDS AND BACKWARDS
