We generally don't want to have general libc functions in the kernel,
although libkern does have some basics.  If you need libc functionality,
then the general idea is to include that functionality in libkern.

Are you sure that's what you want, though?  There are several RTC
drivers--a group of them are in src/sys/dev/i2c/.  These drivers
make use of functions in src/sys/dev/clock_subr.c to convert seconds
to/from a "struct clock_ymdhms".  Is that sufficient for your needs?
