I would use something like the following: 
if ( eval { require Time::Hires } ) {
    # The require was successful
} else {
    # It was unsuccessful
}

The eval with braces will trap the die if Time::Hires is not on your system.

Cheers,
Ovid

Update: Whups! Since I hadn't used Time::Hires before, I wasn't aware of what it does internally. I suspect that autark's correction below is appropriate.
