I have a Problem with parsing dates.

Why does #LSParseDateTime(Now())# produce an error while  #LSIsDate(Now())# answers with 'YES' ? locale is German (Standard)

My ColdFusion Code:

Output:

Now() : {ts '2013-05-15 12:56:27'}

LSIsDate(Now()): YES

LSParseDateTime(Now()):   

The web site you are accessing has experienced an unexpected error.
Please contact the website administrator.

69 :       Now() : #Now()# <br> 
70 :       LSIsDate(Now()): #LSIsDate(Now())# <br> 
71 :       LSParseDateTime(Now()): #LSParseDateTime(Now())# <br>
72 :  

How can this be and how to solve this problem???????
