time_t

Defined in header <time.h> 
typedef /* unspecified */ time_t;
+

Real arithmetic type capable of representing times.

+

Although not defined by the C standard, this is almost always an integral value holding the number of seconds (not counting leap seconds) since 00:00, Jan 1 1970 UTC, corresponding to POSIX time.

+

Notes

The standard uses the term calendar time when referring to a value of type time_t.

+

Example

+

Show the start of the epoch.

+
#include <stdio.h>
+#include <time.h>
+#include <stdint.h>
+ 
+int main(void)
+{
+    time_t epoch = 0;
+    printf("%jd seconds since the epoch began\n", (intmax_t)epoch);
+    printf("%s", asctime(gmtime(&epoch)));
+}

Possible output:

+
0 seconds since the epoch began
+Thu Jan  1 00:00:00 1970
