TIME(2)                       System Calls Manual                      TIME(2)



NAME
       time, nsec - time in seconds and nanoseconds since epoch

SYNOPSIS
       #include <u.h>
       #include <libc.h>

       long time(long *tp)

       vlong nsec(void)

DESCRIPTION
       Both  time  and nsec return the time since the epoch 00:00:00 GMT, Jan.
       1, 1970.  The return value of the former is in seconds and  the  latter
       in  nanoseconds.   For  time, if tp is not zero then *tp is also set to
       the answer.

       Times from time should be stored in and treated as ulongs; this extends
       the range of valid times into the year 2106.

       Time simply calls nsec and returns the value divided by 1000000000.

       Nsec  is  a  system  call.  Previous implementations read /dev/bintime,
       opening that file when first called,  and  maintaining  a  static  file
       descriptor; however, the maintenance of file descriptors in the face of
       process forks is overly complex and prone to error.
