I trying to convert a parsed time of “2005-12-01T18:00:00Z” to the local  
equivalent.

I’m current in -800 (PST) and so and doing the following:  
DateTime.parse(“2005-12-01T18:00:00Z”).new\_offset(-8.0/24)

What I get is very close, but not what I would expect:  
2005-12-01T09:59:59-0800

How do I get this to show 10:00:00? I don’t really care about the  
seconds, so if there is no easy solution, I’ll have to write a method to  
round to the nearest minute.

Thanks,  
Geary

DateTime.parse(“2005-12-01T18:00:00Z”).new\_offset(Rational(-8,24))

Try  
DateTime.parse(“2005-12-01T18:00:00Z”).new\_offset(Rational(-8,24))
