DEC aka Digital Equipment Corporation always used a 64bit counter in their VMS systems, which counted 100ns ticks, not seconds. They had a very funny technical note back in 1988 (they published those to notify sysadmins of changes, procedures, etc):
" This base time of Nov. 17, 1858 has since been used by TOPS-10, TOPS-20, and VAX VMS and OpenVMS. Given this base date, the 100 nanosecond granularity implemented within OpenVMS and the 63-bit absolute time representation (the sign bit must be clear), OpenVMS should have no trouble with time until:
31-JUL-31086 02:48:05.47
At this time, all clocks and time-keeping operations in OpenVMS will suddenly stop, as system time values go negative.
Note that the OpenVMS time display and manipulation routines allow for only 4 digits in the 'YEAR' field. We expect this to be corrected in a future release of OpenVMS sometime prior to 31-DEC-9999."
That's foresight, although they didn't see that they would go under more than 8000 years before that patch was due.
That's why the VAX systems still not phase out at this time, and in fact many banks are still running their systems on VAX and also VMS, so are the US militaries.
Originally posted by finegan Moore's law was that the number of transistors that we could cram on a die doubles every 18 months. Okay, this has actually been perverted into twice the Mhz every 18; for the luddite crowd that at least can understand Megahertz. Let's run with that...
29 Years = 348 months / 18 months = 19.33 iterations of doubling, or 2^19 the clock speed (Today's ballpark 1.8Ghz [Intel can bite me]) = 943718-ish Ghz! or... (remembering to divide by 1024!) 921 Thz Processor.
And I want an SMP board!
Cheers,

Actually it's predicted that Moore's Law will hit a brick wall in 10 or so years, due to physical limitations (things can only go so small).

How do you know? maybe, things start to work with quarks or even smaller So we would have a Computer smaller than a small stone and faster than today's mainframes
Anyway... I don't think we will operate with Computer's we think of today at this time.
May be we will have devices that can read from our brain - so we need to think of a document and voila, we have the document on our screen

ooohhh i don't think that's too good an idea... my thoughts are so erratic and i'm so easily distracted that calling out a document would as soon generate an image of a baboon making faces...
lol agreed. so perhaps its not such a bad idea eh? i wonder what kind of missing dependencies / "hardware" issues i will have to face though... probably something like "Error: not enough swap space in your cerebral cortex. Please find a suitable donor and upgrade..." or "Missing link in neuron synapse. Please contact your neural surgeon"
