Package: libc6 Severity: wishlist For a date in ISO 8601 extended format with "Difference between local time and UTC of day" (§4.2.5.1), the timezone can be written only as ±hh:mm or ±hh.
§4.3.3d says (http://dotat.at/tmp/ISO_8601-2004_E.pdf#): "the expression shall either be completely in basic format, in which case the minimum number of separators necessary for the required expression is used, or completely in extended format, in which case additional separators shall be used in accordance with 4.1 and 4.2." strftime should be able to output the timezone with a colon so a compliant date could be produced without post-processing, and so a locale could default to an ISO 8601 date and time format (other than basic format). Perhaps a new flag could be used, e.g. "%:z". A way to output ±hh if mm==00, or ±hh:mm otherwise, may be useful too. Maybe "%3z" or "%:3z" ("unspecified" per SUSv4: "a minimum field width is specified for any conversion specifier other than C, F, G, or Y"). - Michael -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: arm64 Kernel: Linux 4.1.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init)
