Removing not hiding Date from Timestamp

[mloy3]

Hi, I am trying to do some interval summation with 2 different timestamp. However, i am not able to remove the date that is associated with Expression A(only interested in hh:mm). 

Expression A:
Using a simple formula to add the time stamps together:
time([Work Unit Complete Hour] & ':' & [Work Unit Complete Minute], 'hh:mm')

however, when i check further using:
date(time([Work Unit Complete Hour] & ':' & [Work Unit Complete Minute ], 'hh:mm'),'m/d/yyyy') 
i noticed a bunch of dates associated resulting in correct hh:mm but wrong dd/mm/yyyy when i sum this with another field.

I am not trying to hide the display, but really removing the date associated so that i can add this to another expression.

I am guessing you are must be seeing a date from the year 12/30/1899? It is just a Date for when the value is 0

Thank you Sunny, another colleague pointed out to me that i was using 'm/d/yyyy' instead of 'M/D/YYYY' and that made the whole difference when doing the summation. But yes, i thought what you pointed was an error with the data which i couldnt verify
