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

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's the easiest way to convert this to a timeval? I think timeval is time since Jan 1, 1970? But to calculate this manually everytime seems very tedious. What's the easiest (and fastest) way to do this?

Thanks

You might want to look into std::mktime().

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