Manipulating Times
Posted: Mon Aug 14, 2006 3:13 pm
Hi,
I have run into a problem in a program I'm writing for my client... Heres the story:
I am developing a system that logs the downtime of aircraft due to many different reasons. One of them is maintenance. The maintenance work is based on a 24 hour day. Thus, the log is based on a 24 hour time scale where a user can log a downtime (ex: 05:00 to 14:30). However, the hours of operation for these aircraft is based on an 18 hour day (05:00 to 23:00). What I need to do is to be able to take a 24hr day maintenance log and convert it to an 18hr day to log the downtimes in operation.
Here is an example: Let's say that the aircraft is down for maintenance between the hours of 01:00 and 08:00. I need to convert this 24 hour scale to an 18 hour scale. In actuallity, I need to take the overlapping hours and store them in a variable. The hours of operation are 05:00 to 23:00, thus with the example of 01:00 to 08:00, I would count 05:00 to 08:00. How would I do that?
Its kinda confusing, I know, but any help is greatly appreciated!!!!
Thank you!
