This is a question about the standard bug that many people know
about regarding the date maintained in memory on standard
pc's and many clones. If your computer is on when midnight comes
around, the date will not be changed. I don't know whether this
always happens or only sometimes.

I've got a program which could be left running for many days
for which the date is important.

Does anybody have any simple solution that they've been using?

E.g. replacing the interrupt handler with one of your own
which does the right thing when midnight comes around. The only
problem with this is that the memory locations used by different
models for storing the date and time are bound to change.

In addition does anybody know under exactly what circumstances
this bug will or will not show up?
