How do I get current date/time on the Windows command line in a suitable format for usage in a file/folder name?

Question

Update: Now that it\'s 2016 I\'d use PowerShell for this unless there\'s a really compelling backwards-compatible reason for it, particularly because of the regional setting

Answer 1

I use this (again not region independent (UK))

set bklog=%date:~6,4%-%date:~3,2%-%date:~0,2%_%time:~0,2%%time:~3,2%
