xp system clock and USB

A standard XP computer would not connect to a good DSL network through a router AND no USB drives would recognize a flash drive.

I took the machine back to my bench and without changing a thing, connected a good cable broadband connection and it went on line immediately.  Tried the flash drives and they all read ths time.

Then I noticed the system clock was off by 6 years and some hours.

Does the system clock effect a DSL connection and a USB? Would it prevent a DSL connection and the USB from working properly?

Can't find anything definitive on the web.

Just trying to learn something.

i cannot tell what the date settings affect - it is different for all BIOS models, and even by manufacturer of the mobo; but it will cause a lot of strange things.
so don't wonder about what it affects - just set it right, and test if it's good to go
you may need to replace the cmos battery - CR2032 - should read 3 V

I can't imagine how on the USB.  On DSL, could possibly affect how/when DNS looks for new entries, could be used by some of your software to verify subscription, etc.

I had a computer clock jump ahead a few hundred years and it messed up lots of things.  Every security certificate on the system was suddenly expired.  As soon as I reset the clock, it was good to go again.

Good point on CMOS. If it is bad, the time would be bad and BIOS could "lose it's mind."

I put the new battery in then left it off and unplugged for a day to see if the time and date changed.

So far so good.

Thankss
