Time management

syscalls_timeGet (syscalls_gettime)

GETFROMSTACK(ustack, time_t *, praw, 0);
GETFROMSTACK(ustack, time_t *, poffs, 1);

Set praw to system time in microseconds from system boot. Set poffs to offset configured in syscalls_timeSet. Unused arguments can be set to NULL.

syscalls_timeSet (syscalls_settime)

GETFROMSTACK(ustack, time_t, offs, 0);

Set offset value returned from syscalls_timeSet. This is shared between all processes. It is not used for system time calculations so value interpretation is not specified here. Default offset on boot is 0.
