I'm processing a binary file, and in that file there is a 64bit FILETIME value. This value represents the number of 100-nanoseconds since 1/1/1601. I would like to convert it to a somewhat more usable value, since I eventually will need to display that value as a human readable date.

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. or, since you won't be showing it in such precision, you could cut off a whole bunch from the end, and simply divide by a factor 10^numbers_you_let_off less :)
