PostgreSQL since version 7.2, released 2002-02-04, stores timestamp WITHOUT TIMEZONE as 64-bit. [31] [failed verification] Prior versions already stored timestamp as 64-bit. [citation needed] As of MySQL 8.0.28, released in January 2022, the functions FROM_UNIXTIME(), UNIX_TIMESTAMP(), and CONVERT_TZ() handle 64-bit values on platforms that ...
TIME: for time values (e.g. 15:51:36). TIME WITH TIME ZONE: the same as TIME, but including details about the time zone in question. TIMESTAMP: This is a DATE and a TIME put together in one variable (e.g. 2011-05-03 15:51:36.123456). TIMESTAMP WITH TIME ZONE: the same as TIMESTAMP, but including details about the time zone in question.

CUBRID (/ ˈ k juː b r ɪ d / "cube-rid") is an open-source SQL-based relational database management system (RDBMS) with object extensions developed by CUBRID Corp. for OLTP.The name CUBRID is a combination of the two words cube and bridge, cube standing for a space for data and bridge standing for data bridge.
By default only the current version of a page is included. Optionally you can get all versions with date, time, user name and edit summary. Additionally you can copy the SQL database. This is how dumps of the database were made available before MediaWiki 1.5 and it won't be explained here further.
Version 1 concatenates the 48-bit MAC address of the "node" (that is, the computer generating the UUID), with a 60-bit timestamp, being the number of 100-nanosecond intervals since midnight 15 October 1582 Coordinated Universal Time (UTC), the date on which the Gregorian calendar was first adopted by the bulk of Europe.
In this case, if the transaction's timestamp is after the object's read timestamp, the read timestamp is set to the transaction's timestamp. If a transaction wants to write to an object, but the transaction started before the object's read timestamp it means that something has had a look at the object, and we assume it took a copy of the object ...
If the data is being persisted in a modern database then Change Data Capture is a simple matter of permissions. Two techniques are in common use: Tracking changes using database triggers; Reading the transaction log as, or shortly after, it is written. If the data is not in a modern database, CDC becomes a programming challenge.
