How do I configure Splunk to read events by timestamp?

Hello All our logging events start with a time stamp that looks like this: `00:00:23,746` The data in between the event can have carriage returns, along with different delimiters. For example data can contain `* ~ @ ^ | <>` …..etc. How can I get Splunk to read the events by timestamp? I don’t want any of the data between the time stamps to cause issues.
