1) Modifies the timespec object pointed to by
ts to hold the current calendar time in the time base base.2) Expands to a value suitable for use as the
base argument of timespec_getOther macro constants beginning with TIME_ may be provided by the implementation to indicate additional time bases
If base is TIME_UTC, then
- ts->tv_sec is set to the number of seconds since an implementation defined epoch, truncated to a whole value
- ts->tv_nsec member is set to the integral number of nanoseconds, rounded to the resolution of the system clock

[edit] Parameters
| ts | - | pointer to an object of type struct timespec |
| base | - | TIME_UTC or another nonzero integer value indicating the time base
|
[edit] Return value
The value of base if successful, zero otherwise.
[edit] Notes
The POSIX function clock_gettime(CLOCK_REALTIME, ts) may also be used to populate a timespec with the time since the Epoch.
[edit] Example
Run this code
Output:
Current time: 02/18/15 14:34:03.048508855 UTC
