Hi,

 

I am subtracting the value of two timestamps (today at 7:00 am - first day of the month at 7:00 am) from the same tag, when i do it Excel i get:

This is the correct answer, but when i write the expression in PE i get:

if i do it separately i get the results from the Excel

 

But when i put them in the equation (just add the symbol "-") the result is not the one that should be.

 

I don't know what i'm doing wrong, can someone help me?

 

Thanks,
