Difficulty with DayOfWeek

Ched
Dear All,


 From https://www.freepascal.org/docs-html/rtl/sysutils/dayofweek.html :
DayOfWeek returns the day of the week from DateTime. Sunday is counted as day 1, Saturday is counted as
day 7.

 From
http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/delphivclwin32/DateUtils_DayOfTheWeek.html 
:
DayOfTheWeek returns a value between 1 and 7, where 1 indicates Monday and 7 indicates Sunday

So, for FPC day 7 is saturday while for Delphi it's sunday... Is it a bug, a feature. Shouldn't a warning
be emitted, or so ?

Cheers, Raoul

DayOfWeek is not the same as DayOfTheWeek

DayOfWeek is for USA

DayOfTheWeek is ISO Standard for the rest of the world.
