    Copy and paste below script in file:

    rem Script start here
    rem Timestamp Generator
    set BACKUP_PATH=c:\Backup\
    rem Parse the date (e.g., Tus 17/05/2016)
    set cur_yyyy=%date:~10,4%
    set cur_mm=%date:~4,2%
    set cur_dd=%date:~7,2%
    rem Parse the time (e.g., 11:20:56.39)
    set cur_hh=%time:~0,2%
    if %cur_hh% lss 10 (set cur_hh=0%time:~1,1%)
    set cur_nn=%time:~3,2%
    set cur_ss=%time:~6,2%
    set cur_ms=%time:~9,2%
    rem Set the timestamp format
    set timestamp=%cur_yyyy%%cur_mm%%cur_dd%-%cur_hh%%cur_nn%%cur_ss%%cur_ms%
