offtime, timelocal, timegm, timeoff, gtime, time2posix, posix2time.
- Added prototypes for the currently stubbed out timer functions:
timer_{create,delete,getoverrun,gettime,settime}
When we get sysconf, we can define them in terms of the kernel's notion of
interrupts per second if we so choose. Until then, the constant value
seems to satisfy the requirements presented by ISO C and POSIX, even if it
may lie about the true number of clocks per second.
