Since this is the 2,000th topic in this forum , lets talk about the Y2k bug, or more specifically what caused it. So I ask, how do you keep track of the time and date in your OS?

Since this is the 2,00th topic

That would be the Y0.2K bug.

Seriously though, to save space in my kernel, I use a single bit to represent the number of years since 2009. I've been testing for more than 12 months now and have seen no problems with this approach so far.

Whoops, typo! Fixed it though. So is that a signed bit or non? you would think people would want to access dates prior (think 30 year loan tracker).

From the jump table, item 65:

GetDate rd 1 ; 65. return : EAX=century, year, month,day, each a byte in bcd format.

At the moment, it's going to tell you "not implemented".

I'm just going to combo break these joke answers and give actually how I do it

My current method is to internally keep a Signed 64-bit count of milliseconds as the primary timestamp format. There is also a 32-bit "part-milliseconds" count that is used in the timekeeping code.
(Which makes the internal representation a 64.32 millisecond count)
