    Default Determine hours between two days

    Platform: Hp Compaq 6710b
    Operating System: Ubuntu 17.10
    Development Tools: PERL 5.26, postgresql 9.6, netbeans, vim, python 2.7.14, openjdk 9

    This is not for school or anything like it. I am retired and creating my own poker database, and yes I know of the other poker databases out there.

    My problem is I do not know how to compute hours that overlap two or three days. So if I start at 10:00 A.M. on Sept 18 and leave my seat at 3:00 A.M. on Sept 19 what is the algorithm to compute the hours played?

    Doubtful, but if I start at 10:00 A.M. on Sept 18 and leave my seat at 3:00 A.M. on Sept 20 or Sept 21 what is the algorithm to computer the hours played?

    Thank you;

    Sherman

    Look at the GregorianCalendar and Calendar classes for some methods that may be useful.
    Also the SimpleDateFormat will be useful for converting Strings to Dates.
    If you don't understand my answer, don't ignore it, ask a question.
