Description
The
time function determines the current calendar
time. The encoding of the value is unspecified.
Returns
The
time function returns the implementation's
best approximation to the current calendar time. The
value (time_t)-1 is returned if
the calendar time is not available. If timer is not a null pointer, then the
return value is also assigned to the object it points to.
Implementation Notes
|
The current calendar time is held in the run-time
system with a resolution of 1 second and a range of
2**32 seconds, or 136 years.
|
|
Calendar time is reset to zero each time the run-time
system is restarted, where time zero is 00:00:00 on
Thursday January 1, 1970.
