Function FormatMyDate( strDate, strFormat )
' Accepts strDate as a valid date/time,
' strFormat as the output template.
' The function finds each item in the template and replaces it with the relevant information extracted from strDate
' Template items (example)
' %m Month as a decimal (2)
' %M Month as a decimal (02)
' %B Full month name (February)
' %b Abbreviated month name (Feb )
' %d Day of the month (9)
' %D Day of the month (09)
' %O Ordinal of day of month (eg st or rd or nd)
' %j Day of the year (54)
' %Y Year with century (1998)
' %y Year without century (98)
' %w Weekday as integer (0 is Sunday)
' %a Abbreviated day name (Fri)
' %A Weekday Name (Friday)
' %H Hour in 24 hour format (24)
' %h Hour in 12 hour format (12)
' %N Minute as an integer (01)
' %n Minute as optional if minute <> 0
' %S Second as an integer (55)
' %P AM/PM Indicator (PM)
