An application is a "command" executed by a dialplan priority, such as
Record, Verbose, TrySystem, etc. in your example below.
A function needs to be evaluated inside ${ } and returns a string value
that is substitued in place of the ${ }, such as STRFTIME in your
second example.

The above line might be dangerous. The way %d works is that Record
tries %d=1, then 2 and so on, until it finds a value that doesn't
already exist.
If you have, say, foo%d as the filename, it creates foo1.wav, but then
when you move foo1.wav to a different directory, Record will use foo1.wav
again the next time.
You can avoid that by using ln instead of mv, but when you want to
delete the file, you must remember to do so in both places.
Or you could symlink one directory to another.

That certainly would avoid the problem of reusing the same %d, but would
break if you had two calls in the same second.
