Format specifier to print time(0) in C

Question

We can declare a variable to hold the current time from the system using:

time_t now = time(0);

time(0) can also be use in genera

Answer 1

On most system time_t is define on the same number of bit than integer and is always positive.

In this case you can use:

 printf("time: %u", (unsigned int) time(0));
