How to get accumulated time field not actual time

Question

Hello-
I have a field in a table as "time" however the time data is actually accumulated time over a period of a month not an actual time.  So for example.  We re reporting on Inbound and Outbound phone call duration per employee so we have:
Inbound Duration:  71:45:52 (this is accumlated time, meaning 71 hrs, 45 min, 52 seconds) but when it is displayed in excel or crystal it shows as:
1/2/1900 11:45:52 PM in excel.  I
f you look at the format in excel it should be correct set in the number tab like:  custom [h]:mm:ss
In the actual cell itself it shows the 71:45:52 but in the display that is where it shows the other 1/2/1900 11:45:52 PM
11:45:52 in crystal since it's just a time field in the table
Does anyone know how to correct this on either excel side or crystal?  We have our data in excel which we import into a table to use crystal reports on.
thanks

My formulas were assuming the data was coming in as a datetime value, as it was in your original post.  (Jason was typing his reply while I was typing mine...)  So, the formula with accumulation is (BASIC SYNTAX - make sure the formula editor has this selected, not Crystal Syntax):
global secAccum as number
dim sec as number
dim min as number
dim hr as number
sec = DateDiff("s", CDateTime(1900,1,1,0,0,0), {csr_phones.duration})
secAccum = secAccum + sec
min = int(sec / 60)
hr = int(min / 60)
sec = sec - (min * 60)
min = min - (hr * 60)
formula = cstr(hr, "0") + ":" + cstr(min, "00") + ":" + cstr(sec,"00")
And to show the accumulated seconds:
WhilePrintingRecords
global secAccum as number
dim sec as number
dim min as number
dim hr as number
sec = secAccum
min = int(sec / 60)
hr = int(min / 60)
sec = sec - (min * 60)
min = min - (hr * 60)
formula = cstr(hr, "0") + ":" + cstr(min, "00") + ":" + cstr(sec,"00")
