Thanks, I'll check this out. > > And note that the case of the letters you use in your formatter matter. I don't think I said case doesn't matter. It certainly does... e.g. A vs. a, H vs. h, Y vs. y, ... have significance. As far as I'm aware, and according to http://www.unicode.org/reports/tr35/tr35-31/tr35-dates.html#Date_Format_Patterns there is only one specifier for AM/PM, and that is lowercase 'a', and it is germane only to 12 hr time format strings. 'A' specifies milliseconds in day. The only discussion of case was when I explained why I didn't need to, or rather shouldn't, consider uppercase 'AM'. Those tokens have independent significance in a format string. To clarify for future readers of this thread, I was not implying case doesn't matter. Indeed, I was saying case does matter and looking for lowercase 'a' was appropriate. Thanks for pointing that out.
