Dewey Dunnington commented on ARROW-14471:
------------------------------------------
lubridate does it by ignoring all non-alpha/numeric characters so it'll happily
parse something like "01:::::23::::45" just the same as "012345" or anywhere
inbetween. I forget the exact incantations for strptime, but we could provide a
list of formats we're willing to consider for each of them or preprocess with a
regex to reduce the number of formats we need to consider (i.e.,
{{gsub("[^A-Za-z0-9.]", " ")}}). If that sounds close enough for you I'm happy
to make a PR!
