Extract date / time from source path with custom datetime.xml

I'm hoping someone can help out with something that's been baffling me re: using custom a datetime.xml to extract the date and time from a file's path name. I want to pull out the year, month, day, hour, and minute from the path name for a given set of data. Source would look something like this:


Where 2014 = year, 04 = month, 16 = day, 15 = hour, and 06 = minute. I've tried two variants of custom XML and neither are pulling out either the date nor the time (Splunk only seems to use the file's modtime no matter what I try):

  <define name="_customdate" extract="year, month, day">

  <define name="_customtime" extract="hour, minute">

      <use name="_customtime"/>
      <use name="_customdate"/>

I've even tried doing this with one stanza and that doesn't work either.

  <define name="_masheddate3" extract="year, month, day, hour, minute">

Thoughts on what I might be doing wrong here? Thank you!

At this time you cannot extract time from the filename - only the date.

Thanks, Brian. If that's the case then I should be able to use the _customdate stanza above just to pull out the date - what do I need to do for the timestamp then? I need something inside timePatterns otherwise I get an error.

Splunk should establish the date from the filename (though it may constrain it to MAX_DAYS_AGO/HENCE so if modtime and the filename differ really sharply, be careful with that). Then it should proceed to attempt to establiash both time and date from the event text, using your rules.
