Question

I am in need of some assistance in getting 2 datetimes to split into the hour intervals between them.

This is working with ‘pay’ data, so it needs to be very accurate. I need to take clockin and clockout, and split them into hour intervals.

Example:

clockin = 5/25/2011 1:40:56PM

clockout = 5/25/2011 6:22:12PM

I need that to look like:

5/25/2011 1:40:56PM

5/25/2011 2:00:00PM

5/25/2011 3:00:00PM

5/25/2011 4:00:00PM

5/25/2011 5:00:00PM

5/25/2011 6:00:00PM

5/25/2011 6:22:12PM

I then plan to check those times against a ‘differential’ table to see fi they should have a new paycode. But I’ll worry about the paycode later.

Any help splitting out the times? Prefer C#, but I also have access to MSSQL2000 (which is where we pull the original times)

Answer 1

var hours = new List<DateTime>();
hours.Add(clockin);

var next = new DateTime(clockin.Year, clockin.Month, clockin.Day,
                        clockin.Hour, 0, 0, clockin.Kind);

while ((next = next.AddHours(1)) < clockout)
{
    hours.Add(next);
}
hours.Add(clockout);
