You can use the [Date Filter Plugin](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html) to parse any number of formats into a Time object, which serialises to a ISO8601-compatible representation. It's not clear to me exactly what format strings to recommend, because it depends on whether your inputs zero-pad the day-of-month or hour-of-day fields; for example, the first input you give could be any of: - mar 13 10:36:03 - `MMM d H:mm:ss` (minimal day-of-month; minimal hour-of-day) - `MMM d HH:mm:ss` (minimal day-of-month; zero-padded two-digit hour-of-day) - `MMM dd H:mm:ss` (zero-padded two-digit day-of-month; minimal hour-of-day) - `MMM dd HH:mm:ss` (zero-padded two-digit day-of-month; zero-padded two-digit hour-of-day) I would advise using the above-linked docs to define appropriate format strings. ---

I want to know how to convert multiple formats into one format. ---

Please read the linked documentation, try it for yourself, and come back with a description of what you tried, what you expected to happen, and what behaviour you observed if you are still having problems. ---

After matching the timestamp with the target to the timestamp by matching, the time is automatically reduced by 8 hours. ---
