In my website (PHP & MYSQL), I have on functionality which tracks the in-out data from swipe card system and displays first in and last out in report.
This I have done. But, now I am having an issue for the employee working in night shifts. The swip card system is in MSSQL Server.
And the data is stored in one of the table with fields cardno, iodatetime. The field iodatetime stores the data for in and out both. Consider the following scenario
Night Shift Employee ‘A’ comes in the office at 17:00PM (Consider: Date 9th Aug, 2012) and leaves on 9:00AM (Date: 10th Aug, 2012).and I want to show in-out data date wise like
Date 9Aug 10thAug
In Time 18:00 9:00AM
Out Time 23:58(if left for a break)
Total Hours 5:58
Please let me know the approach for calculating the total hours datewise for employee working in shifts.
Your help will be highly appreciated.
Thanks in advance.
