Few problems in DT module docs

[Petr Schreiber]

Hi Eros,

I found few problems in DT module docs:

- syntax is displayed using 3 different fonts ( normal, code font, code font without color )

- DT_GetWeekDayName
--> %DT_USE_LONG_FORM and %DT_USE_SHORT_FORM have swapped the descriptions

- DT_Minute
--> wrong syntax ( for DT_Second )


Bye,
Petr
