|TIME(3)||Library Functions Manual||TIME(3)|
time() function returns the value of time in seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time (UTC).
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.
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.
time() system call first appeared in Version 1 AT&T UNIX and used to return time in sixtieths of a second in 32 bits, which was to guarantee a crisis every 2.26 years. Since Version 6 AT&T UNIX,
time() scale was changed to seconds, extending the pre-crisis stagnation period up to a total of 68 years.
