Defined in header <time.h>
time_t time( time_t *time );

Returns the current calendar time encoded as a time_t object.

Contents

Parameters

time - pointer to a time_t object to store the time in or NULL

Return value

Current calendar time encoded as time_t object on success, (time_t)(-1) on error. If the argument is not NULL, the return value is equal to the value stored in the object pointed to by the argument.

Notes

The encoding of calendar time in time_t is unspecified, but most systems conform to POSIX specification and return a value of integral type holding the number of seconds since the Epoch. Implementations in which time_t is a 32-bit signed integer (many historical implementations) fail in the year 2038.
