i am new to logstash and i am stuck with following problem:
I have something like a timestamp: 1703220054
First 2 digits indicates year YY 17
Next 2 digits indicates MM 03
Next 2 digits indicates dd 22
Next 2 digits hour hh 00
Next 2 digits minutes mm 54
I want to bring it to timestamp value for @timestamp.
Do you have any good advice for me?
