* date,touch: allow timezone offsets in datesRon Yorston2021-09-171-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | Allow ISO 8601 style dates to include a timezone offset. Like the '@' format these dates aren't relative to the user's current timezone and shouldn't be subject to DST adjustment. - The implementation uses the strptime() '%z' format specifier. This an extension which may not be available so the use of timezones is a configuration option. - The 'touch' applet has been updated to respect whether DST adjustment is required, matching 'date'. function old new delta parse_datestr 624 730 +106 static.fmt_str 106 136 +30 touch_main 388 392 +4 date_main 818 819 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 141/0) Total: 141 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* build system: drop PLATFORM_LINUXRon Yorston2020-08-131-2/+0
| | | | | | | | | | | | | | | PLATFORM_LINUX is a hidden configuration option which is disabled by default and enabled at over a hundred locations for features that are deemed to be Linux specific. The only effect of PLATFORM_LINUX is to control compilation of libbb/match_fstype.c. This file is only needed by mount and umount. Remove all references to PLATFORM_LINUX and compile match_fstype.c if mount or umount is enabled. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
