How to special date time format to timestamp format

[akif_bal]

I have a log type that I cannot manipulate. How can I convert the Time format in the log to timestamp format?
Example log: "0001 021222 095725 00240541029896158 11 00 00 0000000000 000 0"
Date and time that comes with the log: 021222 095725
thanks in advance for your help

Are you trying to do it via logstash?

If yes, you can use GROK Pattens to match it and using mutate filter you can convert any field to date format.

Not sure what a date format do you have.

filter {

	grok {
		match => { "message" => "%{NUMBER:somenum}%{SPACE}%{NUMBER:date1}%{SPACE}%{NUMBER:date2}%{SPACE}" }
	}

	mutate { add_field => { "[date]" => "%{[date1]}%{[date2]}"} }

	date { 
		match => ["date", "MM/dd/yyyy HH:mm:ss"  ]   # put your format
	}
}

I want to replace the log time recorded by the system in timestamp

Thank you, I will try

Code:

filter {

	grok {
		match => { "message" => "%{NUMBER}%{SPACE}%{NUMBER:[@metadata][date]}%{SPACE}%{NUMBER:[@metadata][time]}%{SPACE}" }
	}

	mutate { add_field => { "[@metadata][datetime]" => "%{[@metadata][date]}%{[@metadata][time]}"} }

	date {
		match => ["[@metadata][datetime]", "ddMMyyHHmmss"  ] # put your format
		timezone => "Asia/Dubai" # Set your own or leave it as it is
		target=> "@timestamp" # default destination field
	}
}

Result:

    "@timestamp" => 2022-09-16T13:17:01.000Z,
     "@metadata" => {
            "date" => "160922",
            "time" => "171701",
        "datetime" => "160922171701"
    }

I want to use the datetime in the log record because the datetime in the log and the time the logs are read do not match.

our grok filter

 grok {
      match => {"message" => ["%{WORD:TERMINAL_NO} %{MONTHDAY:day}%{MONTHNUM:month}%{YEAR:year} %{HOUR:hour}%{MINUTE:minute}%{SECOND:second} %{WORD:CARD_NUMBER} %{WORD:Event1} %{WORD:Event2} %{WORD:Event3} %{WORD:Event4} %{WORD:Event5} %{WORD:Event6}"] }

      remove_field => "message"
    }
    mutate {
      add_field => { "date" => "%{day}%{month}%{year} %{hour}%{minute}%{second}" }
    }

    date {
      match => ["date", "MM/dd/yyy HH:mm:ss" ]
    }```

result :

[
  {
    "TERMINAL_NO": 13,
    "day": 2,
    "month": 12,
    "year": 22,
    "hour": 11,
    "minute": 59,
    "second": 59,
    "CARD_NUMBER": 1115481172,
    "Event1": 11,
    "Event2": 0,
    "Event3": 0,
    "Event4": 0,
    "Event5": 0,
    "Event6": 0
  }
]```
