I have scripted FnDT.bat to return the current date and time in a string that is formatted like YYYYMMDD_HHMNSS.

The syntax for using FnDT.bat is:

call FnDT DateTime

Where DateTime is a call directed environment variable that will contain the current date and time in a YYYYMMDD_HHMNSS formatted string.

FnDT.bat contains:

@echo off                              if \{%1\}==\{\} @echo Syntax: call FnDT DateTtime&goto :EOF                              setlocal                              if exist "%TEMP%\FnDT.vbs" goto doit                              @echo dDate = Now>"%TEMP%\FnDT.vbs"                              @echo sDateTime = Year^(dDate^) ^& Right^(100 + Month^(dDate^), 2^) _>>"%TEMP%\FnDT.vbs"                              @echo.          ^& ^Right^(100 + Day^(dDate^), 2^) ^& "_" ^& Right^(100 + Hour^(dDate^), 2^) _>>"%TEMP%\FnDT.vbs"                              @echo.          ^& Right^(100 + Minute^(dDate^), 2^) ^& Right^(100 + Second^(dDate^), 2^)>>"%TEMP%\FnDT.vbs"                              @echo WScript.Echo sDateTime>>"%TEMP%\FnDT.vbs"                              :doit                              for /f "Tokens=*" %%a in ('cscript.exe //nologo "%TEMP%\FnDT.vbs"') do (                               set DT=%%a                              )                              endlocal&set %1=%DT%
