How do you parse two time formats in Splunk?

[bobojesus]

The first time format is

Fri Dec 21 11:17:30 2018
the other one is 
2018-12-21T11:17:31.051061

I was wondering how i would line break this, and also, how would I format the time format to accept both times?

By accident I ran into the same problem. 

The brute force solution looks like: 

   | eval my_time1=strptime(genZeit, "%Y-%m-%dT%H:%M:%S%:z")
   | eval my_time2=strptime(genZeit, "%Y-%m-%dT%H:%M:%S.%3N%:z")
   | eval my_time=if(isnotnull(my_time1),my_time1,my_time2)

Try to convert the time with both of the possible time formats (be careful: my example will not reflect the time format of the original question), take the result which is not null.

Although this problem is different to the OP's problem, there is another way to handle multiple date formats, e.g. by using coalesce and the multiple date formats in descending order of probability

   | eval my_time=coalesce(
        strptime(genZeit, "%Y-%m-%dT%H:%M:%S%:z"),
        strptime(genZeit, "%Y-%m-%dT%H:%M:%S.%3N%:z"))

Cool, works like a charm 😁

As @PickleRick said, you should Fix _time on indexing phase, not in search time! Do always real data onboarding and ensure tuhat you have Events correctly in your indexes.
You could/should use @bowesmana ’s eval in your transforms.confs INGEST_EVAL.

While it might "work" it's definitely a bad idea to handle the main event's time this way. The _time field is the most important time field associated with an event and - very very importantly - it's the basic field for initial event filtering so just assigning "something" to it and then later handling time in search time is very unusual, confusing and ineffective performance-wise.

In recent splunk versions there are INGEST_EVAL in transforms.conf. With it you could select correct timestamp field and convert it to epoch if needed. Here is one old post where you could see the idea how it works. https://community.splunk.com/t5/Getting-Data-In/How-to-apply-source-file-date-using-INGEST-as-Time/m...

If a single file has more than 1 timestamp format then the developers should get a serious paddling and either split the events or pick one format and stick to it. Until that happens, you can force Splunk to look for both with a custom datetime.xml file:

Each unique format should be tied to a sourcetype. You create base configs that tell Splunk how to read the timestamp and break the events properly relative to the sourcetype. In theory, you write the sourcetype rules once for each log format and you tie new events to that sourcetype

[bobojesus]

Yeah I know that. What I was wondering is there a way to properly format two different time formats located in one log file

[skoelpin]

Well yeah.. If they are in the same log file then assuming they are of the same type, they should be in he same format. If not, then you can route them to a different sourcetype

Use the documentation for sourcetype override. Have timestamp parsing for both sourcetypes as per your needs. While pulling data from index, pull both sourcetypes:
