| # Examples: | ||
| # <pre> | ||
| # "PT20.345S" -- parses as "20.345 seconds" | ||
| # "PT15M" -- parses as "15 minutes" (where a minute is 60 seconds) | ||
| # "PT10H" -- parses as "10 hours" (where an hour is 3600 seconds) | ||
| # "P2D" -- parses as "2 days" (where a day is 24 hours or 86400 seconds) | ||
| # "P2DT3H4M" -- parses as "2 days, 3 hours and 4 minutes" | ||
