  • Maintaining date and time with time zone rule changes
    Patent number: 8400881
    Abstract: A method and system for maintaining date and time information correctly across rule changes for time zones is provided. A time maintenance system provides rules for converting dates and times between various time zones and a common time zone. When the time maintenance system receives a date and time in a designated time zone, it converts the date and time to a date and time in the common time zone based on a provided rule. The time maintenance system then stores the converted date and time along with an identification of the rule used to convert the date and time to the common time zone. The time maintenance system may then receive an indication of an overriding rule that overrides an existing rule for converting a date and time between the designated time zone and the current time zone. The time maintenance system then updates the stored date and time when the rule has been overridden in such a way as to indicate that the original date and time is no longer correct and to indicate the new rule.
