st: Formatting of dates

["I.Mosca" <I.Mosca@uvt.nl>]

Dear Fellows,

we have an entry that looks like the following: 
1-1-2002 00:00:00
It is a string variable str19 %19s.

We'd like to transform it into a numerical/date format, but the information we want to keep is only the year.
How can we do that? 

Thanks for your help.
