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]

Thanks a lot! I see that your solution works excactly how I want it to work when opening you file.
But when copying it to my file, it gives a different result. (Just the same as the timestamp). Can't figure out what causes the difference.

May be your timestamp has milliseconds as well.

 

Could you send me your file?

Hi Zubair,

 

I managed to solve the last problem myself regarding that the timestamp was also in milliseconds. This solved my problem I e-mailed you. 

The other issue that it needs to see the alarms seperatly is still an issue though. Don't know if you have ideas on this aswell?

 

Thanks
