How can I access a more accurate time in a Command Prompt aka “DOS”

Question

I am running a batch script to retrieve information from a device. Tieing this up with a separate log file requires accuracy greater than the minute accuracy I can get using time /t.

This question has a method I wasn't aware of using wmic, but that only allows access to time up to 1 second accuracy (technically, you can ask for milliseconds - but the answer is always NULL)

Answer 1

I had forgotten that the command prompt has some built in variables.

Use %TIME%

set dt=%DATE%-%TIME%
echo %dt%

gives 26/10/2011-15:08:19.09
