iTerm2 VS Leap Second

• Versatility
  iTerm2 supports a wide range of features such as split panes, multiple tab management, and hotkey-activated terminal windows, making it highly versatile for different workflows.
• Customization
  Offers extensive customization options, including themes, color schemes, and key bindings, allowing users to tailor the terminal to their preferences.
• Advanced Features
  Includes advanced functionality like instant replay, which allows users to rewind their terminal session, and integration with automation tools like AppleScript.
• Performance
  Designed to be efficient and responsive, ensuring it performs well even with multiple sessions and tabs open simultaneously.
• Integrations
  Seamless integration with macOS features such as native notifications, fullscreen mode, and support for external editors.
• Community Support
  Active community and comprehensive documentation, which can be very helpful for troubleshooting and learning advanced configurations.

Possible disadvantages

• Mac-Only
  iTerm2 is exclusive to macOS, which means users on other operating systems cannot utilize its features.
• Complexity
  The sheer number of features and customization options can be overwhelming for beginners, requiring a learning curve to utilize efficiently.
• System Resource Usage
  iTerm2 may consume more system resources compared to simpler terminal emulators, which could be a concern on lower-end hardware.
• Update Frequency
  Occasional updates can introduce bugs or unexpected behavior, requiring users to adjust settings or find workarounds.

• Keeps civil time aligned with Earth's rotation
  Leap seconds keep UTC within 0.9 seconds of UT1, which is based on Earth's actual rotation. Clock time therefore stays tied to the position of the Sun and does not drift away from the solar day.
• Supports astronomy and celestial navigation
  Telescope pointing, satellite tracking and some legacy navigation systems assume UTC is close to UT1. Leap seconds avoid the need for separate corrections in those systems.
• Small, frequent adjustments instead of big jumps
  Adding single seconds when needed avoids a much larger correction later, such as a leap minute or leap hour, which would be more disruptive and harder to explain to the public.
• Internationally standardized process
  The IERS decides on leap seconds and announces them about six months ahead. This gives a single authoritative, globally coordinated mechanism that timekeeping systems can follow.

Possible disadvantages

• Causes software and infrastructure failures
  A 23:59:60 timestamp breaks assumptions in many systems, such as monotonic time and 60-second minutes. Past leap seconds have caused crashes, hangs and outages in operating systems, databases and cloud services.
• Unpredictable schedule
  Earth's rotation speed varies irregularly, so leap seconds cannot be predicted far in advance. Systems that need long-term time calculations cannot know future UTC offsets, so they need frequent updates.
• Inconsistent handling across systems
  Some systems step the clock, some repeat a second, and others smear the extra second over hours, as Google and AWS do. These differences can leave clocks briefly disagreeing, which hurts distributed systems, logging and financial timestamping.
• Being phased out
  In 2022 the CGPM voted to stop using leap seconds by or before 2035. Anything built around them has an uncertain long-term future, and the planned replacement will let UTC drift from solar time.
• Website details unverified
  I can't access https://www.leapsecond.co, so these points describe leap seconds as a concept, not that site's specific product or service. Check the site directly for its features, pricing and quality.
