Subject: date: support parsing of ISO-8601-with-"T" dates
X-Git-Tag: v8.13~20
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=df9cd0a426a9b52ddfcd1c17e368a89fa3c6fbde;p=thirdparty%2Fcoreutils.git

date: support parsing of ISO-8601-with-"T" dates

Thanks to an improvement in gnulib's parse-datetime module,
commands like this now succeed (output manually indented):
    $ ./date -u -d 2004-02-29T16:21:42.33+07:00 +%FT%T.%N%z
		   2004-02-29T09:21:42.330000000+0000
* tests/misc/date: Add a test to exercise the new-in-gnulib
parsing of ISO8601-with-"T" dates.
* NEWS (New features): Mention it.
* gnulib: Update, to pull in this parse-datetime improvement.

 ** New features
 
+  date now accepts ISO 8601 date-time strings with "T" as the
+  separator.  It has long parsed dates like "2004-02-29 16:21:42"
+  with a space between the date and time strings.  Now it also parses
+  "2004-02-29T16:21:42" and fractional-second and time-zone-annotated
+  variants like "2004-02-29T16:21:42.333-07:00"
+
   md5sum accepts the new --strict option.  With --check, it makes the
   tool exit non-zero for any invalid input line, rather than just warning.
   This also affects sha1sum, sha224sum, sha384sum and sha512sum.
