Hi ,

There are two fields named "start_time" and "end_time" extracted from logs and displayed in the format "03/21/14 01:11:13".Can someone tell the search query on how to calculate the differnce between two time and display the difference in terms of seconds.For example

Start_time End_time duration
03/21/14 01:11:13 03/21/14 01:11:15 2

Use the convert command to change them too epoch time. Then use eval to get the difference. In seconds.

I often find the various functions of convert to be confusing to beginners, so here's a working example:

| stats count | eval startTime = "03/21/14 01:11:13" | eval endTime = "03/21/14 01:11:15" | convert mktime(*Time) timeformat="%m/%d/%y %H:%M:%S" | eval diff = endTime - startTime
