Determine Shift based on TimeStamp

[KevinJan]

Hi All,

I need help to determine the shift based on the time stamp of my data set. 

Day Shift = 6:00:00 AM to 6:00:00 PM

Night Shift = 6:00:00 PM to 6:00:00 AM (the next day)

Any help is much appreciated.

Thanks

column=
VAR _A =
TIME ( 6,00,00 )
VAR _B =
TIME ( 18,00,00 )

RETURN
IF (
[Time Coulmn] >= _A
&& [Time Coulmn] <= _B,
"Day Shift","Night Shift" )

Hi @KevinJan ,

maybe this will help.

if DateTime.Time([time]) > Time.From("6:00:00") and DateTime.Time([time]) < Time.From("18:00:00") then "Day Shift" else "Night Shift"

Maybe I am mistaken, but while looking for a similar solution, I believe this is not enough. I have successfully defined the night and day shift by time, but what happens when the last part of the night shift is accounted for in the wrong day? For example, the night shift has 6 hours that happens in the following morning, but needs to be counted as the same shift as the night in which is began. Does this formula account for that?

Hi @villasenorbritt ,
for this requirement you should calculate another column that will tell you the date the value is counted.

if DateTime.Time([time]) <= Time.From("6:00:00") then DateTime.Date([time]) - #duration(1,0,0,0) else DateTime.Date([time])
