time difference issue

[changwoo]

start_time = > 2014-02-13T22:57:15+0900

end_ time = > 2014-02-13T23:59:54+0900

how can i get the time difference ??

i tried

convert timeformat="%Y/%m/%d %H:%M:%S" mktime(start_time) AS StartTime_epoch mktime(end_time) AS ResolvedTime_epoch | eval total=round((ResolvedTime_epoch-StartTime_epoch)/60/60/24)

Try this,

your_base_search 
| eval epoch_st = strptime(start_time, "%Y-%m-%dT%H:%M:%S%z") 
| eval epoch_et = strptime(end_time, "%Y-%m-%dT%H:%M:%S%z")
| eval epoch_diff = epoch_et - epoch_st
| eval dur=tostring(epoch_diff, "duration")

oh well, if your fields are actually called start_time and end_time, the new fields should come out fine. However, they do not show in the event text (_raw), but you can use them in tables, charts, stats etc.
