how to use TimeGE?

I am using PI system explorer Analses, and this is set to periodic evaluation at intervals of 1 hour.

 

CWOutlet temperature may only exceed 90'F for 96 hours each calendar year.  am I right in thinking this phrase will create a count of hours that this is true?

I keep evaluating and I only get "0" for an output, when I know the answer should be 81.

 

StartTime = parsetime(concat("01-Jan-", year("*")))

TimeGE(CWOutlet,StartTime,'*',90)/3600

 

the equation is mapped to an attribute '96HourRule'

I have backfilled the expression starting on january 1st, i have checked it in, and I have refreshed.  still 0.  is the units of TimeGE seconds?

this is my third straight day trying to figure out how to use this function... please help me.
