In FreeTDS, the "default" and "en_US" locales have the following values of
"date format" defined in locales.conf:
[default]
date format = %b %e %Y %I:%M:%S:%z%p
[en_US]
date format = %b %e %Y %I:%M:%S:%z%p
language = us_english
charset = iso_1
Is there a reason that FreeTDS chose to separate the seconds and
milliseconds with a colon (':'), rather than a dot ('.')? A few users of
tds_fdw recently ran into issues with this:
https://github.com/GeoffMontee/tds_fdw/issues/13
Because of the ISO 8601 standard, I think most applications expect a dot
separator between seconds and milliseconds.
http://en.wikipedia.org/wiki/ISO_8601
These days, it may make sense to use ISO 8601 as the default "date
format",
since it is pretty universal. If FreeTDS is going to have a new release
soon, maybe it would be worth changing the default date format?
I don't remember the history but must be quite old.
Yes, default can change. As long is well documented I don't see the point
keeping the colon.
Thanks for the reply!
Changing the colon to a dot sounds good to me.
Would it be worth changing the default completely to an ISO
8601-compatible format? That would probably be something like:
[default]
date format = %Y-%m-%dT%H:%M:%S.%z
The main difference between that and ISO-8601 is that it wouldn't
contain the timezone offset. strftime uses %z for the timezone offset,
but FreeTDS uses %z for the milliseconds.
Thanks,
Geoff
