          Issue ID: 13368
           Summary: std.datetime.monthToString should be public
           Product: D
           Version: unspecified
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Phobos

          Reporter: kevin.lamonte at gmail.com

I am implementing a logging library and need to convert DateTime.month to a
3-letter month abbreviation, e.g. 0 --> "Jan".  monthToString (which is used by
toSimpleString()) already has this functionality.

Note that to!string(DateTime.month) returns a fully-lowercase month name, which
is not what I need.

Making monthToString public would also give one easy access to "January",
"February", etc.
