In addition to the BC_MATH package, there's some new-fangled extension to
PHP that does the same kind of stuff.
I'm not quite sure how you are going to get the 32 bytes into a string
suitable for sending *TO* either of those packages, however...
I'm guessing you'll have to read 32 bits, throw that into BC_MATH,
multiply by 0xFFFFFFFF, grab the next 32 bits, and add that in BC_MATH...
Then, you'll have to divide by 100-nanoseconds and/or subtract enough
seconds to get to whatever time format you want to use.
