[R] time from excel with XLConnect

[Knut Krueger]

When I read a time hh:mm:ss from a excel sheet with gdata read.xls it is 
as expected.
When I read the time with readWorksheet I get 1899-12-31 00:20:00 UTC.  
I would prefer XLConnect because it does not nee perl installed but the 
data coming with XLConnect  is not usable.
