Actually the documentation does say what {{{time}}} does; I just didn't
read it all this time.

{{{date}}}{{{date(FORMAT)}}}{{{time(FORMAT)}}}{{{modification-time(FORMAT
)}}}
"These macros refer to the #+DATE keyword, *the current date*, and the
modification time of the file being exported, respectively."

Apologies.

And thanks to everyone for giving their time to reply to this.
