Unfortunately, DOS can't do arithmetic from the command line
(not even greater than or less than commands--only equals).
To do what you asked, you would have to include
an IF statement for **every** possible iteration of the RTC.
What you need is a real programming language.
With every OS it shipped, M$ *used* to include a QBASIC interpreter
(a stripped-down version of its QuickBASIC compiler). No mas.[1]

That's not really a huge deal, however:

...or even

Here in the 21st Century, there are many, many options, e.g.:

have ALWAYS shipped with GCC (the GNU Compiler Collection).
