Hi,

Java developer making the switch. I have timestamps stored in Oracle as  
a long (gotten from java.sql.Timestamp - milliseconds from some day in  
1970). Is there a way to convert that long back into a Ruby  
Date/DateTime/Time . Any of these would do.

Did not find a method in the library…

Thanks,

Mike
