    The AM/PM suffix only makes sense on a 12-hour system, not a 24-hour clock. If you use an 24-hours based day, you already know whether the time is in the morning or evening. Otherwise, the 8 O'Clock needs the AM/PM suffix to discriminate between 8:00 (8 AM) and 20:00 (8 PM). It's a ridiculous format, and that mistake is as grave as the function is coded. It'd be best to use the date-format as specified in the users' settings, or to use a predefined format. Making up your own format requires owning a country.

      That is quite spectacularly bad. - Unused parameter - Misnamed function (it is getting the hour part suffix, not Time) - Using strings to manage date/time info, and relying on the exact string (i.e. 2 != 02) - Incorrect coding or non-standard representation (01-24 instead of 00-23) - Duplicating framework functionality (myDateTime.ToString("hh tt")) - Repeat code in case blocks instead of a single test for all included conditions Anyone spot any more?

      No need to set a string to return from the function. A simple return "AM"; or return "PM"; would suffice.

        Or... Assuming the string has only military time with no date:

        string strReturn = DateTime.Parse(DateTime.MinValue.ToString("MM/dd/yyyy ") + strTime).ToString("tt");

        If it has date and time:

        string strReturn = DateTime.Parse(strTime).ToString("tt");

          your solution is different from original. What if the parameter string is not a number or number any other than one in switch? The original will return empty string while yours - eather throw or return PM instead.

            I know what you mean mate... the solution I put was just to show that whole function can be redundant. If I have to code it I will make sure of all exception and validations on client and server...

              You should focus on making it future-proof.

                  The Army (at least) took 2400 as the end of the day...and never acknowledged 0000 as existing. :p

                  So I rounded up my camel Just to ask him for a smoke He handed me a Lucky, I said "Hey, you missed the joke." My Mu[sic] My Films My Windows Programs, etc.

                    Then one second after that would be 240001 or 000001?

                      000001 But we just started the new logs at 0001Z. That minute inbetween was just ignored. Actually, come to think of it, we never used 2400Z, either. The day ended at 2359Z and the next started at 0001Z. :p

                        ISO 8601 allows 24:00 as the end of the day, so it would be PM; AM starts at 00:00 (not that ISO 8601 recognizes AM/PM of course).

                        If you are dealing with instantaneity, 12:00:00 and 24:00:00 (or 0:00:00, if you prefer) are neither AM nor PM: the first is Noon and the second is Midnight.

                        Just think of it as evolution in action.

                          No need to set a string to return from the function. A simple return "AM"; or return "PM"; would suffice.

                          That's not really so much a horror as a stylistic choice, though one which I would also change as you have suggested there. Some people say that a single point of return is better because you don't have to look through the whole function to find escape points, and though I disagree with that (for one thing your function should be short enough it isn't a problem) I can see what they're getting at.

                            I disagree with the single point of return as well. To me it requires some degree of convoluting the code just to reach that point. I tried that approach for a while but I found myself having to add code rather than getting straight to the purpose of it. But then I've always tried to avoid having to take those few extra CPU cycles to get from point A to point B if point A++ gets the job done faster.

                              It's also wrong : "24" is "AM" :) Cheers

                              But there is a fix for that issue...

                              string ampm = GetTime("Blahblahblah", strTime);

                              if (strTime = "24" && ampm = "PM")
                              {
                              ampm = "AM";
                              }

                              See! It's easy. ;P
