Hi,
How to calculate the difference between 2 given times.
Eg.
Input:
HHMMSSXX
04:45:12:45
04:42:54:23
How to write a program to calculate the difference between 2 given time like the above mentioned?
Is there any built-in function?
It's quite emergency.Someone plz give me a reply as early as possible. |

This is a tricky one. The date difference can be calculated using COBOL functions. I have stated an example below.
The following example shows how to calculate a due date that is 90
days from today. The first eight characters returned by the CURRENT-DATE function
represent the date in a 4-digit year, 2-digit month, and 2-digit day format
(YYYYMMDD). In the example, this date is converted to its integer value. Then 90
is added to this value, and the integer is converted back to the YYYYMMDD format.
| Code: |
01 Date-1-YYYYMMDD Pic 9(8).
01 Date-2-YYYYMMDD Pic 9(8).
01 Integer-Form Pic S9(9).
...
Move Function Current-Date(1:8) to Date-1-YYYYMMDD
Compute Integer-Form-Date-1 = Function Integer-of-Date(Date-1-YYYYMMDD)
Compute Integer-Form-Date-2 = Function Integer-of-Date(Date-2-YYYYMMDD)
Compute day-diff-dates = Integer-Form-Date-2 - Integer-Form-Date-1
|
This gives difference of days between dates.
However, time difference will have to be calculated with program logic (I think!)
parse your time HH:MM:SS:NN as
| Code: |
01 WS-TIME.
05 WS-HR PIC 9(02)
05 FILLER PIC X(01) VALUE ':'
05 WS-MM PIC 9(02)
05 FILLER PIC X(01) VALUE ':'
05 WS-SS PIC 9(02)
05 FILLER PIC X(01) VALUE ':'
05 WS-NN PIC 9(02)
MOVE INPUT-TIME TO WS-TIME.
MOVE INPUT-OTHER-TIME TO WS-TIME-2 (defined in similar fashion as WS-TIME). |
Now calculated HH, MM, SS and NN difference separately. and club output in WS-TIME-RESULT which should be defined in similar fashion as WS-TIME. Fillers would be ':'. |

Geo,
Try this code for the difference in time. If the start time is greater than the end time, the code assumes passage of one day.
| Code: |
01 START-HHMMSSDD.
05 START-HH PIC 9(2).
05 FILLER PIC X.
05 START-MM PIC 9(2).
05 FILLER PIC X.
05 START-SS PIC 9(2).
05 FILLER PIC X.
05 START-DD PIC 9(2).
01 END-HHMMSSDD.
05 END-HH PIC 9(2).
05 FILLER PIC X.
05 END-MM PIC 9(2).
05 FILLER PIC X.
05 END-SS PIC 9(2).
05 FILLER PIC X.
05 END-DD PIC 9(2).
01 NO-DAYS PIC 9(3).
01 START-TIME PIC 9(11).
01 END-TIME PIC 9(11).
01 DIFF-TIME PIC 9(11).
01 DIFF-HHMMSSDD.
05 DIFF-HH PIC 99.
05 FILLER PIC X VALUE ':'.
05 DIFF-MM PIC 99.
05 FILLER PIC X VALUE ':'.
05 DIFF-SS PIC 99.
05 FILLER PIC X VALUE '.'.
05 DIFF-DD PIC 99.
PROCEDURE DIVISION.
MOVE '04:45:12.45' TO START-HHMMSSDD.
MOVE '04:42:54.23' TO END-HHMMSSDD.
IF END-HHMMSSDD < START-HHMMSSDD
THEN
MOVE 1 TO NO-DAYS
ELSE
MOVE 0 TO NO-DAYS
END-IF.
MOVE 0 TO START-TIME
END-TIME.
COMPUTE START-TIME = START-HH * 60
COMPUTE START-TIME = (START-TIME
+ START-MM) * 60
COMPUTE START-TIME = (START-TIME
+ START-SS) * 100
COMPUTE START-TIME = (START-TIME
+ START-DD)
COMPUTE END-TIME = NO-DAYS * 24
COMPUTE END-TIME = (END-TIME
+ END-HH) * 60
COMPUTE END-TIME = (END-TIME
+ END-MM) * 60
COMPUTE END-TIME = (END-TIME
+ END-SS) * 100
COMPUTE END-TIME = (END-TIME
+ END-DD
COMPUTE DIFF-TIME = END-TIME - START-TIME.
DIVIDE DIFF-TIME BY 100 GIVING DIFF-TIME
REMAINDER DIFF-DD.
DIVIDE DIFF-TIME BY 60 GIVING DIFF-TIME
REMAINDER DIFF-SS.
DIVIDE DIFF-TIME BY 60 GIVING DIFF-TIME
REMAINDER DIFF-MM.
MOVE DIFF-TIME TO DIFF-HH.
DISPLAY 'START-HHMMSSDD : ' START-HHMMSSDD.
DISPLAY 'END-HHMMSSDD : ' END-HHMMSSDD.
DISPLAY 'DIFF-HHMMSSDD : ' DIFF-HHMMSSDD.
GOBACK.

With START-HHMMSSDD = '04:45:12.45' and END-HHMMSSDD = '04:42:54.23', result is:
| Code: |
.START-HHMMSSDD : 04:45:12.45
.END-HHMMSSDD : 04:42:54.23
.DIFF-HHMMSSDD : 23:57:41.78
|
With START-HHMMSSDD = '04:42:54.23' and END-HHMMSSDD = '04:45:12.45', result is:
| Code: |
.START-HHMMSSDD : 04425423
.END-HHMMSSDD : 04451245
.DIFF-HHMMSSDD : 00:26:22.00
|
If you have problems wit the code, let me know.

OOPs,
With START-HHMMSSDD = '04:42:54.23' and END-HHMMSSDD = '04:45:12.45', result is:
| Code: |
.START-HHMMSSDD : 04:42:54.23
.END-HHMMSSDD : 04:45:12.45
.DIFF-HHMMSSDD : 00:02:18.22
