    The last modification date stamp (and with DELWATCH 2.0+ also the file deletion date stamp, and since DOS 7.0+ optionally also the last access date stamp and creation date stamp), are stored in the directory entry with the year represented as an unsigned seven bit number (0–127), relative to 1980, and thereby unable to indicate any dates in ...

  3. Year 2038 problem - Wikipedia

    en.wikipedia.org/wiki/Year_2038_problem

    Unix time has historically been encoded as a signed 32-bit integer, a data type composed of 32 binary digits (bits) which represent an integer value, with 'signed' meaning that the number can represent both positive and negative numbers, as well as zero; and is usually stored in two's complement format.

  4. Thomas write rule - Wikipedia

    en.wikipedia.org/wiki/Thomas_write_rule

    Enforcing the Thomas write rule only requires checking to see if the write timestamp of the object is greater than the time stamp of the transaction performing a write. If so, the write is discarded In the example above, if we call TS(T) the timestamp of transaction T, and WTS(O) the write timestamp of object O, then T2's write sets WTS(C) to ...

  5. Timestamp-based concurrency control - Wikipedia

    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 ...

  7. Timestamp - Wikipedia

    en.wikipedia.org/wiki/Timestamp

    The term "timestamp" derives from rubber stamps used in offices to stamp the current date, and sometimes time, in ink on paper documents, to record when the document was received. Common examples of this type of timestamp are a postmark on a letter or the "in" and "out" times on a time card .

  8. Change data capture - Wikipedia

    en.wikipedia.org/wiki/Change_data_capture

    The most common forms of SCD are type 1 (overwrite), type 2 (maintain history) or 3 (only previous and current value). SCD 2 can be useful if history is needed in the target system. CDC overwrites in the target system (akin to SCD1), and is ideal when only the changed data needs to arrive at the target, i.e. a delta-driven dataset .

  9. Template:Timestamp - Wikipedia

    en.wikipedia.org/wiki/Template:Timestamp

    Due to MediaWiki and browser caching, these variables frequently show when the page was cached rather than the current time. Alternative: To generate a formatted date stamp with the current date and time, use five tildes (~~~~~) to output: 04:54, 20 December 2024 (UTC). In some templates, five tildes is the preferred way to add the date.
