In order to make it more clear that ticks should be used for timers and realtime should be used for timestamps / displaying the date/time, getuptime() was renamed to getticks() and getuptime2() was renamed to getuptime(). Servers, drivers, libraries, tests, etc that use getuptime()/getuptime2() have been updated. In instances where a realtime was calculated, the calculation was changed to use realtime. System calls clock_getres() and clock_gettime() were added to PM/libc.
