Nothing wrong with not having seen it, but I default to time stamps like this for log files, I use it all the time in scripts. I even also do it manually and have an alias in my .bashrc I call ‘now’ that spits out a call to date with that format string. This is, obviously, useful for organizing and sorting and finding files & folders by date & time. (And, hopefully obviously, creation & mod times on files are completely unreliable for this once you factor in copying & archiving.)
