The following code:
<?php
new DateInterval('PT0.5S');
Resulted in this output:
Warning: Uncaught DateMalformedIntervalStringException: Unknown or bad format (PT0.5S)
But I expected this output instead:
DateInterval object with 500 milliseconds
The ISO Duration string can have the seconds set to a decimal fraction. I found this bug when Postgres returns Intervals with decimal fractions for seconds if required when returning a ISO8601 duration string.
From Wikipedia:
The smallest value used may also have a decimal fraction,[39] as in "P0.5Y" to indicate half a year. This decimal fraction may be specified with either a comma or a full stop, as in "P0,5Y" or "P0.5Y".

If necessary for a particular application the lowest order component may have a decimal fraction. The decimal fraction shall be divided from the integer part by the decimal sign specified in ISO 31-0: i.e. the comma [,] or full stop [.]. Of these, the comma is the preferred sign. If the magnitude of the number is less than unity, the decimal sign shall be preceded by a zero (see ISO 31-0);
