I'm not much expert with DOS but you can try out the following , i found it by searching in google:

for /f "tokens=*" %%a in ('"C:\DOS\time TIME_VAR"') do set YOURVAR=%%a
echo.%YOURVAR%

Some of you may still have not found the answer to this question ...

The MS-DOS is not always convenient and it is even quite limited in certain situations. When you want to retrieve the result of a command in a variable to be able to address directly, you have two solutions.

The first is to write the output into a file and then read it but then forget, there are more effective after all. The command For can process line by line the contents of a file or the result of an order, we will use it:

For example, if you want to write the result of your command in a variable named result, Do this

for /f "delims=" %%a in ('your command here') do set result=%%a

Nota: Remember the "single quotes" to each side of your variable.
Do not forget that %% a not contain a row of the result of your order at each iteration of the loop.

And now, that's it.
