A minor point

[dragosmg]

Are there any formats we still do not support? With the exception of locale-specific ones on Windows?

[rok]

strftime supports: %a %A %w %d %b %B %m %y %Y %H %I %p %M %z %Z %j %U %W %x %X %% %G %V %u
strptime on Windows supports: "%d", "%H", "%j", "%m", "%T", "%S", "%q", "%M", "%U", "%w", "%W", "%y", "%Y", "%R", "%T"
strptime on non-Windows in additionally supports: "%a", "%A", "%b", "%B", "%Om", "%OS", "%I", "%p", "%r", "%z"
parse_date_time supports on Windows: "H", "I", "j", "M", "S", "U", "w", "W", "y", "Y", "R", "T", "%H", "%I", "%j", "%M", "%S", "%U", "%w", "%W", "%y", "%Y", "%R", "%T"
parse_date_time on non-Windows supports: "a", "A", "b", "B", "Om", "p", "r", "%a", "%A", "%b", "%B", "O%m", "%p", "%r"

I'm not sure where to put this information :)

[dragosmg]

Would this statement be accurate : "for parse_date_time() we support all formats on Linux and macOS. On windows we don't support ... "? And we stick to parse_date_time() only?

[nealrichardson]

@rok could you instead add a note to the binding (see #14387) that explains which tokens are not supported (since it seems like most everything is)? Or make a note that punts on the whole question like the base R docs to and just say "support is platform dependent" and mostly identical to R.

Just browsing some old PRs before we're in a release rush...is this PR still relevant/is there anything I can do to put it over the line?

[rok]

Hey @paleolimbot I'll take a look tomorrow!

[rok]

@paleolimbot sorry this took a while to get to. Please check if this make sense.

[paleolimbot]

Thanks!

(Just waiting for CI to do its thing)
