regarding Is there software for CMOS under iS-DOS? and I decided to intervene.

Only trouble - the kernel probably never needs a date.
At least it doesn’t use it anywhere. Therefore if
if you want a date, you need to ask the system for the residential address
command line vector (there are a lot of letters, but little sense -
it was easier to just describe where to get it yourself) and directly
to this address with an offset like -3 (maybe inaccurate!!!)
contains a 2-byte date.
AM> I wrote a letter, I look and the file has the correct date...
The editor pushed it into place using the method described above.
Just catch the moment when the program wants a date, not
command line vector for example or not something else _impossible_!
You will have to write down the correct date at interruptions.

uh... I don’t understand what you mean, but see above - as it should.
I once wrote here about the Unified Standard for Use
System Date and Time in the Is-Dos Operating System
and wanted him, but Kondratyev wrote that all this is not like
in a normal OS and therefore...
Meanwhile, there is still a question - after all, the watches are as different as dirt.
The date seems clear - on interruptions. What about time?
Where should I put it or how to recognize it? :-/ After all, in the descriptor
The file has 2 bytes for time.
