Description of problem:
man tmpfiles.d contains:

   Age
       The date field, when set, is used to decide what files to delete when cleaning. If a file or directory is older than the current time minus
       the age field, it is deleted. The field format is a series of integers each followed by one of the following postfixes for the respective
       time units:

       s, min, h, d, w, ms, m, us


However, it does not say which suffix means what. These are my guesses:

second, minute, hour, day, week, ???, ???, ???

I could have a wild guess that 'ms' is millisecond and 'us' is microsecond, but then I would have completely zero idea what 'm' stands for.

Can you please clarify in the man page what those suffices mean?

Thanks.
