Hi @karunagaraprabh , as I said, if you have a multivalue field, you cannot do calculations, so you have to define if you want to take for calculation one of the epochtimes (e.g. the first one) or split your event in as many events as the number of values in printedA_epoch. In the first case use something like my above hint: your_search
| rename ...
| rex field=printedA_epoch "^(?<printedA_epoch>\d+)"
| eval indextime=_indextime
| eval fdata=round(((indextime-printedA_epoch)/86400),0)
| eval diffdata=indextime-printedA_epoch
| table indextime ... in the second case, try something like this: your_search
| spath
| rename jobs.job.job-manifest.end-range.side-a.printed-timestamp AS printedA_timestamp
| eval printedA_epoch=strptime(printedA_timestamp,"%Y-%m-%dT%H:%M:%S.%3N-%z")
| mvexpand printedA_epoch
| eval indextime=_indextime
| eval fdata=round(((indextime-printedA_epoch)/86400),0)
| eval diffdata=indextime-printedA_epoch
| table indextime printedA_epoch fdata diffdata Ciao. Giuseppe
