If it is already in the _time field, it is probably already in epoch time format, so try this

| eval Date=strftime(_time,"%F")
| eval Time=strftime(_time,"%T")

| table date,time

Error in 'rex' command: Encountered the following error while compiling the regex '^(?<date>\d\d\d\d-\d\d-\d\d)\s+(?<time>\d\d:\d\d:\d\d\.\d\d\d': Regex: missing closing parenthesis.

Hi @bhaskar5428,

sorry I missed a paranthesi at the end of the regex, please try this:

| rex field=_time "^(?<date>\d\d\d\d-\d\d-\d\d)\s+(?<time>\d\d:\d\d:\d\d\.\d\d\d)"

Ciao.

Hi @bhaskar5428,

let me understand: are you spoeaking of search time extraction or timestamp configuration?

if search time extraction, you could use a regex like this:

| rex "^(?<date>\d\d\d\d-\d\d-\d\d)\s+(?<time>\d\d:\d\d:\d\d\.\d\d\d"

Ciao.
