Group Consecutuve rows (timestamps)
Hi,
I have some trouble with grouping consecutive timestamps as 1. The Data is kind of alarmdata, so a row only appears when alarm is on. Every consecutive second it is "on" that means it is the same alarm that is still "on". So as you see:
timestamp 22:29:05 until 22:29:14 is consecutive. <---- one alarm = duration 9 seconds.
timestamp 22:29:16 until 22:29:20 <--- other alarm. etc.
I would want to group the rows that have consecutive seconds. Therefor this table will consist of 4 different alarms.
I think the best way is to creat a alarm starttime with the first timestamp per alarm and a column endtime.

Please see attached file.
I added an Index Column then
I have added 2 custom columns "AlarmStart" and "AlarmEnd"
AlarmStart=let mytime=[timestamp]-#duration(0, 0, 0, 1), myindex=[Index] in try if Table.SelectRows(#"Added Index",each [Index]=myindex-1)[timestamp]{0}=mytime then null else [timestamp] otherwise [timestamp]
