A little more experimenting shows that changing *date*->seconds* to *date->seconds* (no asterisk) in

   (seconds->date
        (+ (date*->seconds ts  #f) (* timezone 60 60))
         #f))


guarantees the time offset always is correct wrt the original UTC time. So it seems that *(seconds->date (date*->seconds date #f) #f)* is not always symmetric? *sql-timestamp->srfi-date* produces a *date** so I thought I needed to use *date*->seconds*.

But I still have the problem that *sql-timestamp->srfi-date* isn't always converting the SQL timestamp properly.
