strftime day and month: Splunk vs Python


My question is about day and month components of a date without leading zeroes.

Python docs provide %-d and %-m respectively.

Splunk docs do not show these options.  Splunk, however, has %e which seems to be the same as %-d.  I did not find any option for decimal month number.

I have tried and Splunk seems to accept %-d and %-m

Is it standard feature that I can rely on? Is it implementation dependent?

Did I miss something in Splunk docs?

Hi @pm771 

I think the Splunk docs are not very detailed about this and could be improved, for sure.  I believe it's just python libraries in the Splunk backend so, yes, any valid python strftime() modifiers will work (dependent on the installed Splunk python version).

Here's a run anywhere example I tried.


| makeresults
| eval epoch=relative_time(_time, "@month")
      ,date1=strftime(relative_time(epoch, "@month"), "%Y-%m-%d")
      ,date2=strftime(relative_time(epoch, "@month"), "%Y-%m-%e")
      ,date3=strftime(relative_time(epoch, "@month"), "%Y-%-m-%-d")
      ,date4=strftime(relative_time(epoch, "@month"), "%Y-%#m-%#d")


Note the %e has a leading whitespace so stick to either %-d or %#d.

Hope this helps.
