How do I convert the following date stamp into integers

[kganesan (Karthick Ganesan)]

Hello.

I have the following date stamp info at the start of my log line and I need to convert them to integers.
Log Line:
2019-06-17 14:05:00.202
Expected Output:
Year: 2019
Month: 06
Date: 17
Hours: 14
Minutes: 05
Sec: 00
Millisec: 202

All the above fields should be in integer for my visualization purposes.

Is there any easy way to do it?
Any help providing me with an example syntax is appreciated

    mutate { add_field => { "someField" => "2019-06-17 14:05:00.202" } }
    date { match => [ "someField", ISO8601 ] target => "[@metadata][ts]" }
    ruby {
        code => '
            epochMS = event.get("[@metadata][ts]").to_f * 1000
            dateTime = DateTime.strptime(epochMS.to_s, "%Q")
            event.set("Year", dateTime.year)
            event.set("Month", dateTime.month)
            event.set("Date", dateTime.day)
            event.set("Hours", dateTime.hour)
            event.set("Minutes", dateTime.minute)
            event.set("Sec", dateTime.second)
            event.set("Millisec", epochMS.to_i % 1000)
        '
    }

It has been converted to date time format but when I open the parsed logs in kibana I am getting the following errors.

Also the date hour min info are all wrong. only the captured field I named "loggedTime" seems right.

This is the filter I used:
date
{
match => [ "endTime", ISO8601 , "YYYY-MM-dd HH:mm:ss.ZZZ" ]
target => "loggedTime"
}
ruby {
code => '
epochMS = event.get("loggedTime").to_f * 1000
dateTime = DateTime.strptime(epochMS.to_s, "%Q")
event.set("Year", dateTime.year)
event.set("Month", dateTime.month)
event.set("Date", dateTime.day)
event.set("Hours", dateTime.hour)
event.set("Minutes", dateTime.minute)
event.set("Sec", dateTime.second)
event.set("Millisec", epochMS.to_i % 1000)
'
}

When I opened Kibana - the index I created I got th following error.
"
Discover: failed to parse date field [-61566890962977] with format [epoch_millis]: [failed to parse date field [-61566890962977] with format [epoch_millis]]

My guess is that your index mapping maps Date as a date. If you rename that field to dayOfMonth do the errors go away?
