While the idea of regularly changing clocks to manage daylight savings has been losing appeal over the years, it is likely to remain in effect in many locales for years to come. Since neither time zone was observing daylight savings, the time shift required only adding up the difference in biases and applying it to the date/time. The need to do this effectively arises often, even in systems where time zones are handled relatively well. Syntax: Defines a date that is combined with a time of day with fractional seconds that is based on a 24-hour clock.
