I found that fractional seconds were doubled when using the timezone feature of Time in Sequel's named_timezones extension (which uses TZInfo for the timezone object), and traced the problem to this code. There is no subsecx being modified in the utc_to_local call below this, and I'm not sure why you would want to add in the fractional seconds unless you assumed the timezone conversion would drop the existing fractional seconds (TZInfo doesn't drop fractional seconds).
