I need to convert a Date object into a TimeWithZone object representing the beginning of that day in a given time zone. The following approach works, but seems too convoluted as it requires me to convert the date to a string: ?> date = Date.parse("2010-02-17") => Wed, 17 Feb 2010 >> ActiveSupport::TimeZone['Eastern Time (US & Canada)'].parse(date.to_s) => Wed, 17 Feb 2010 00:00:00 EST -05:00 >> ActiveSupport::TimeZone['UTC'].parse(date.to_s) => Wed, 17 Feb 2010 00:00:00 UTC 00:00 Is there a better way I'm missing?
