merge revision(s) 276f6a225d18561cbe5282b798cb4e416c66079f,95bef7b69a6fb42687a6200b338060be307259f5: [Backport #17352]

	Don't double fractional seconds when passing timezone object to
	 Time.new

	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).
