time()
|
|
Returns the current time as calendar time. If you need a broken-down
|
|
time, either use the RTC API or gmtime(). However, this function is
|
|
already based on mktime() (for hardware reasons) so it would be much
|
|
faster to use the RTC API if possible.
|
|
If timeptr is not NULL, it is set to the current time, that is, the
|
|
value that is returned.
