I was referring to the multiple timezones that are abbreviated to "CST", as described in a sibling comment.
But you bring up another good example. I've worked with people who write times as "PST" or "EST" all year long. This bothers me in its simple incorrectness -- I do know what they mean but I hate autocorrecting them.
But I've also worked with people in parts of Indiana, and Mexico. When they say "CST" at any time of the year, they might mean it precisely!
My strategy is to write, e.g. "8:30 AM US/Pacific". Which probably annoys other people, but at least it's precise and unambiguous. I think it's less awkward than the equivalent "America/Los_Angeles".
Full list of US lower 48 timezones: US/Arizona, US/Central, US/East-Indiana, US/Eastern, US/Indiana-Starke, US/Michigan, US/Mountain, US/Pacific.
