Convert Format of apiStartTime to Epoch

Motivator

Hi, I wonder whether someone may be able to help me please.

I'm trying to change the "apiStartTime" which is in the following format 'Sat Mar 5 00:00:00 2016' including the apostrophes to an epoch time so I can perform some date calculations.

So I've been looking at the Splunk documentation here and I thought I'd understood the variables I need to use and then convert and I put together the following:

|eval startTime=strptime(apiStartTime, "%a %m %d %H:%M:%S %Y")|convert timeformat="%d/%b/%Y" ctime(startTime)

Unfortunately though this isn't working, and I'm not sure why.

I just wondered whether someone could possibly look at this please and let me know where I've gone wrong.

Many thanks and kind regards

Chris

The first half of your SPL correctly converts an apiStartTime string into epoch form. The second half converts the epoch back into a string, which may not be necessary, depending on why you need an epoch.

This is reviving a very old thread, but I will still post this in case someone else needs it. Try:

|eval startTime=strptime('apiStartTime', "'%a %b %e %H:%M:%S %Y'")

Hi, thank you for coming back to me with this and for the clarification on my query.

The problem is, is that in isolation this line

|eval startTime=strptime(apiStartTime, "%a %m %d %H:%M:%S %Y") isn't converting the api time to epoch.

Kind Regards

If apiStartTime truly includes apostrophes, then the format string should be "'%a %m %d %H:%M:%S %Y'".

Hi, thank you for this. I just had to make a minor change to "'%a %m %b %H:%M:%S %Y'", which now works great.

In my initial testing I had incorporated a ' but with a % beforehand, because in the documentation it suggested to use something as a literal character add a % beforehand. I obviously misinterpreted this.

Once again thank you for your help and kind regards

In strptime and strftime format strings, all characters are literal except those preceded by '%'. Use "%%" to get a literal '%'.

Ahh I see.

That's a lot clearer now. Thank you.
