Pull up following revision(s) (requested by martin in ticket #216):
share/man/man9/todr.9: revision 1.17 sys/arch/sh3/dev/rtc.c: revision 1.9 sys/dev/clock_subr.c: revision 1.17-1.22 sys/dev/clock_subr.h: revision 1.22 sys/fs/msdosfs/msdosfs_conv.c: revision 1.10 tools/compat/compat_defs.h: revision 1.98 tools/compat/dev/clock_subr.h: revision 1.1-1.2 usr.sbin/makefs/msdos/Makefile.inc: revision 1.6 clock_secs_to_ymdhms(9) takes seconds as a time_t, not int. -- Make this compile- and usable from userland as well. -- Add a slightly stripped down version of sys/dev/clock/clock_subr.h to make this code available for tools. -- Reformulate an overflow test so it can be used in tool builds (i.e. does not depend on netbsd specific macros). -- Make msdosfs time conversion use the y/m/d/h/m/s conversion functions from clock_subr.c and compile that into the userland (and tools) makefs as well. -- Copy definitions of __type_min(t), __type_max(t), and some related macros, from <sys/cdefs.h>, for use when building tools. -- Revert previous; test secs > __type_max(time_t) again, now that __type_max is available in tools/compat/compat_defs.h. -- If HAVE_NBTOOL_CONFIG_H is set, then include "nbtool_config.h", because this file is compiled as part of tools/makefs. -- Counting leap years was fine while we had 32bit time_t - but now it is not a good idea for dates far away in the future. For dates in the year 2000 or later, use arithmetic instead (since the repeating periods are well aligned). Should fix PR 49144. -- Avoid overflowing the "year" value by making the field uint64_t. Adapt arguments and local variables accordingly. This now fixes PR 49144 for real. -- Adapt formats for debug printfs to clock_subr type changes.
