In line with @franknarf1 's comment in #1523 :
What's the consensus: would you prefer the new feature to print out time offset with respect to UTC, or the full tz name (as it is PRed now)?

https://en.wikipedia.org/wiki/ISO_8601

ISO 8601 timestamps would be ideal IMO:

Time zones in ISO 8601 are represented as local time (with the location unspecified), as UTC, or as an offset from UTC.

Many other languages (e.g. Spark, Presto, Go) also understand the T delimiter between YMD and HMS... I also think base R's strptime should be improved to handle ISO 8601 timestamps natively but that's another issue...

It would be amazing if fwrite could write ISO timestamps & fread could read them but that feels a bit like scope creep -- I think the improvement to upstream in base R would be better...

Thanks @fparages! I've invited you to be project member. (You'll need to accept the invite before GitHub adds you.)
