Big numbers are fun. Here's some stupid stuff I thought of while reading about this.
The number is 2^74,207,281 - 1. Naively stored like a normal integer in memory, that's roughly 75 MB of RAM just to store the number. Compare that to your 64-bit time_t and imagine how long a duration of time could be represented by such a large number. Stored on 3.5" floppy disks for some reason, that's roughly 50 disks just to store the number.
Edit: Duh, bits, not bytes. I leave my mistake here for posterity.
