Format a log message with a timestamp

[misteryuku]

How do i format a log message with a timestamp so that when i send the log message to the splunk server i am able to see the timestamp when i open up the search app.

Most events don't require any special timestamp handling. Splunk automatically recognizes and extracts their timestamps...

Configure timestamp recognition

yes that's the timestamp splunk assigned to the event.
some rare occasions you need to point to splunk where is the timestamp and what format,you do that as per the link i put in my answer.

The timestamp created is at the left hand side of the event row. is that it?

Why sometimes the value of the timestamp is none when i add events to the splunk server?
"In most cases, Splunk will do the right thing with timestamps, but there are situations where you might need to configure timestamp handling." Is that the reason why?
