I wouldn't say ISO 8601 is unsupported. Only that in some cases the
grammar definitions would allow easier usage from external text
elements - from a config file for example. Similar to the pattern
syntax symbols/tokens, but in a less granular manner which would make
conditional parsing easier. It would also be less ambiguous since the
hierarchical definitions are explicit.

Appendix A. ISO 8601 Collected ABNF
  date-century
  ...
  period


config.file
  format=/var/log/date-year/date-month/date-mday

vs.

config.file
  format=/var/log/YY/MM/dd
  ...
  format=/var/log/YYYY/MM/dd


>From the application side you can enforce the tokens and do
substitution easier than char parsing. Log4j ConversionPattern, does
this from the properties file essentially doing the same thing Joda
does for char parsing.

All the data continuously generated in your IT infrastructure 
contains a definitive record of customers, application performance, 
security threats, fraudulent activity, and more. Splunk takes this 
data and makes sense of it. IT sense. And common sense.
