Just do "man gettimeofday", or if that fails, Google "Linux manual gettimeofday".

Notice that "struct timeval" has only two fields: tv_sec field is commented plainly with the word "seconds" and the "tv_usec" field is commented plainly with the word "microseconds".

1. So I think this means the resolution is in microseconds.
2. You need this when you want to get the time of day as a raw integer value, and not a formated text value for the date and time. You can use the result as a seed value for a pseudo-random number generator, for example.
3. Wait a minute, am I doing your homework for you?
