Time zone abbreviations for both Standard Time and Daylight Saving Time are shown exactly as they appear in the database. See strftime and its "%Z" field. Some of zone records use 3 or 4 letter abbreviations that are tied to physical time zones, others use numeric UTC offsets.
In 1994 DEC sold the Rdb division to Oracle Corporation where it was rebranded Oracle Rdb. As of 2020, Oracle is still actively developing Rdb, with over half of the codebase developed under Oracle's ownership. [4] Version 7.0 ran on OpenVMS for VAX and Alpha, version 7.1 on Alpha only, and versions 7.2 to 7.4 on Alpha and IA-64 (Itanium).
Each zone line for a zone specifies, for a range of date and time, the offset to UTC for standard time, the name of the set of rules that govern daylight saving time (or a hyphen if standard time always applies), the format for time zone abbreviations, and, for all but the last zone line, the date and time at which the range of date and time ...
Software timekeeping systems vary widely in the resolution of time measurement; some systems may use time units as large as a day, while others may use nanoseconds.For example, for an epoch date of midnight UTC (00:00) on 1 January 1900, and a time unit of a second, the time of the midnight (24:00) between 1 January 1900 and 2 January 1900 is represented by the number 86400, the number of ...

A specified oracle is typically associated with formalized approaches to software modeling and software code construction. It is connected to formal specification, [8] model-based design which may be used to generate test oracles, [9] state transition specification for which oracles can be derived to aid model-based testing [10] and protocol conformance testing, [11] and design by contract for ...
A downgrade attack, also called a bidding-down attack, [1] or version rollback attack, is a form of cryptographic attack on a computer system or communications protocol that makes it abandon a high-quality mode of operation (e.g. an encrypted connection) in favor of an older, lower-quality mode of operation (e.g. cleartext) that is typically provided for backward compatibility with older ...
