It would be very useful to have the ability to use the datetime variable with the 'variable set' command.
This way, when an album or movie is played you could also set a field in the database to contain the current date&time. You could then sort on the date field to show recently played items or items that have not been played for ages. This could be used for a TV show database to also datestamp a show when it has been watched - if it hasn't been watched yet the field would be blank, therefore combining two functions into one.
I would like the following command to work with datetime variable...
Variable Set
Category: Music
Variable: lastplayed
Value: %datetime>u%
