How to remove duplicate events if all data is identical except the time and duration fields?

Hey, Fellow Splunkers I have multiple duplicated events, all data on the event is identical to the exception of the time. I'm attempting to filter based on Alert ID; however, both events have the same alert id, but different times and Duration: for example: Oct 31 00:16:50 alert: 123 Duration 200 Oct 31 00:18:50 alert: 123 Duration 300 Does Splunk have a compare operator to SORT the differences between the time or Duration which will help me eliminate the duplicates? The only concept the Duration could be random. Thank You,
