NAME

       time - report how long a command takes

SYNOPSIS

       time command

EXAMPLES

       time a.out	   # Report how long a.out takes

       time ls -l *.c	   # Report how long ls takes

DESCRIPTION

       The  command  is executed and the real time, user time, and system time (in hours, minutes, and seconds) are printed.  Shell scripts cannot
       be timed.

SEE ALSO

       times(2).

NAME

     time -- get time of day

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <time.h>

     time_t
     time(time_t *tloc);

DESCRIPTION

     The time() function returns the value of time in seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time.

     A copy of the time value may be saved to the area indicated by the pointer tloc.  If tloc is a NULL pointer, no value is stored.

     Upon successful completion, time() returns the value of time.  Otherwise a value of ((time_t) -1) is returned and the global variable errno
     is set to indicate the error.

ERRORS

     No errors are defined.

SEE ALSO

     gettimeofday(2), ctime(3)

STANDARDS

     The time() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').

HISTORY

     A time() function appeared in Version 2 AT&T UNIX.  It returned a 32-bit value measuring sixtieths of a second, leading to rollover every
     2.26 years.  In Version 6 AT&T UNIX, the precision of time() was changed to seconds, allowing 135.6 years between rollovers.

     In NetBSD 6.0 the time_t type was changed to be 64 bits wide, including on 32-bit machines, making rollover a concern for the far distant
     future only.  Note however that any code making the incorrect assumption that time_t is the same as long will fail on 32-bit machines in
     2038.
