You're right, the T has to be there to resolve any ambiguity between
month and minute.

PT3M23S is ISO 8601 notation for 3 minutes and 23 seconds.

Then it won't be able to be parsed as an actual time.

The data format is machine data, as are geo-coordinates as well.
The machine data has to remain with the human data so that
discrepancies between the two aren't allowed to occur.

When thinking about other time formats, consider how 3 seconds would
be marked up, or even days and weeks.
