Not a map, but there is a list of semi-standard time zone abbreviations here: https://en.wikipedia.org/wiki/List_of_time_zone_abbreviation...

CST and BST are a couple of common ones with overloads. Use the ISO standard for your time stamps guys. I have to work with one API that uses these ambiguous abbreviations in a key time stamp field (faceplam).

It was a total brain fart though – I know what EST is and I know that my time zone is CET; just had some neurons misfiring!

WDYM? There is exactly one time zone called EST.

The “real” EST means “Eastern Standard Time”. The top commenter thought it was “European Standard Time” which could for instance be equivalent to WET (“Western European Time”). What your parent comment is suggesting is a joke to come up with other definitions which would fit EST to other time zones. E.g. MST (“Mountain Standard Time”) could be EST (“Eagle Summer Time”).

thanks for explaining, i meant something like xkcd would do

Sounds like something Randall from xkcd would cook up.
