DateTime day ending 24:00 (midnight)

Question

I have a customer that wants to see midnight represented as the end of the prior day.

Example

var date = DateTime.Parse("1/27/2010 0:00");
Console.WriteLine(date.ToString(<some format>));

Display:

1/26/2010 24:00

I believe this is valid in the ISO 8601 standard. (see this)

Is there any way to support this in .net (without an ugly string manipulation hack)?

Answer 1

I guess you'll need a custom formatter for the dates. Look at the IFormatProvider and ICustomFormatter interfaces.

This and this may also help.
