Zero Downtime Upgrade of Timezone Data

The process of upgrading timezone data to reflect up-to-date Governmental Daylight Saving Time rules and to change existing data to reflect these new rules is accomplished in a streamlined, simplified, and automated manner without the need of any downtime or significant impact on the availability of timezone data for queries and DML operations.

Zero downtime upgrade of timezone information removes the burden of database administrators to schedule a downtime window for this operation, removing complexity and obstacles towards continuous 24x7 availability of any database system.
