XSD uses ISO 8601 durations and allows a sign before the initial "P".

It would appear PT1M means 60 or 61 seconds. P1D means 23, 24 or 25
hours. P1M means 28..31 days etc. Timedelta would have no option but to
stick to seconds:

   P29389453.2345S

but then, why not simply use a number:

   29389453.2345
