This article explains MySQL date‑time data types, compares DATETIME and TIMESTAMP, shows how to map them to Java types, provides SQL examples, and demonstrates several methods for timezone conversion between MySQL and Java applications.
This article explains the physical and philosophical notions of time, the challenges of representing time in computing, and provides a comprehensive guide to Java's date‑time APIs—including System.currentTimeMillis, System.nanoTime, java.util.Date, java.sql.Timestamp, Calendar, SimpleDateFormat, and the modern Java 8 classes such as Instant, LocalDate/Time, ZonedDateTime, and DateTimeFormatter—while highlighting common pitfalls and best practices.
This article introduces Java 8's new date‑time API, explains the shortcomings of the old java.util.Date classes, and provides practical examples for using Instant, LocalDate, LocalTime, LocalDateTime, ZonedDateTime, Duration, Period and DateTimeFormatter in real projects.
This article explains how to use Python's time and datetime modules to calculate workdays between two dates, determine week counts, and retrieve dates offset by a given number of days or months, providing reusable utility scripts with clear code examples.
This article provides a comprehensive overview of Python’s three core time-handling modules—time, datetime, and calendar—explaining key concepts such as epoch, UTC/GMT, time zones, DST, and demonstrating how to retrieve, format, and convert dates and times using their APIs.
This article demonstrates how to use Python's built-in Turtle module to create an analog clock that displays the current time, including step-by-step explanations of setting up the Turtle objects, drawing the clock face, hands, and updating them in real time with code examples.
This article investigates why MySQL master‑slave replication can exhibit a one‑second difference in datetime fields when using server‑side prepared statements, analyzing binlog generation, InnoDB rounding, and providing code examples, root‑cause explanation, and mitigation strategies.
This article provides a concise overview of Python's three core time modules—datetime, time, and calendar—explaining their design, key concepts like epoch, UTC, DST, and demonstrating how to obtain, convert, and manipulate dates and times with practical code examples.
This article introduces six versatile Python libraries—Pyglet, Peewee, Bottle, Invoke, Splinter, and Arrow—that help developers quickly solve common tasks, from multimedia handling and database access to web APIs, automation, and date‑time processing, while remaining robust for larger projects.
