Steps to reproduce:

1. Configure logrt item for a Zabbix agent on Linux:

1. 1. logrt item for file /tmp/test
   2. Log time format = yyyy-MM-dd hh:mm:ss
   3. Preprocessing rule: Regexp: .* -> 20\0 (= whatever string, add "20" in front of it)
2. echo "23-08-31 18:22:05 testing" >> /tmp/test

Result:

= string conforms to the configured log time format but local time is not parsed.

Expected:

It is expected that the local time is parsed according to the log time format from the preprocessed string.
