When you see a "Z" at the end of a timestamp, it signifies "Zulu time," which is another name for Coordinated Universal Time (UTC).
The "Z" symbol comes from military tradition, ensuring uniformity worldwide by avoiding confusion with local time zones and is not adjusted for local daylight saving or other time changes.
Zulu Time is used where precise timing and global coordination are essential such as Aviation, Military, meteorology, science and data centres.
