Following up on @Joey's and @Kees' answers to make them instantly usable.

On the command line:

FOR /f %a IN ('WMIC OS GET LocalDateTime ^| FIND "."') DO SET DTS=%a
SET DateTime=%DTS:~0,4%-%DTS:~4,2%-%DTS:~6,2%_%DTS:~8,2%-%DTS:~10,2%-%DTS:~12,2%
echo %DateTime%

In a BAT file:

@echo off
REM See http://stackoverflow.com/q/1642677/1143274
FOR /f %%a IN ('WMIC OS GET LocalDateTime ^| FIND "."') DO SET DTS=%%a
SET DateTime=%DTS:~0,4%-%DTS:~4,2%-%DTS:~6,2%_%DTS:~8,2%-%DTS:~10,2%-%DTS:~12,2%
echo %DateTime%

Example output:

2014-10-21_16-28-52
