Convert month / day / year / time to timeval in C / C ++

Question

In C / C ++, suppose I have the following values:

int year = 2010; int month = 6; int day = 15; int hour = 14; int minute = 52; int seconds = 34; int microseconds = 141231; 

What is the easiest way to convert this to timeval? I think timeval is the time since January 1, 1970? But figuring it out manually each time seems very tedious. What is the easiest (and fastest) way to do this?

thanks

Answer 1

You can use mktime(3) to convert the struct tm structure to time_t . After you have time_t , you can copy it and your microseconds directly to the struct timeval structure.

Answer 2

You might want to learn std::mktime() .
