Set a fake date in your browser globally using Tampermonkey
PLEASE INSTALL THE NEW SCRIPT: https://greasyfork.org/en/scripts/531462-fake-date-with-controls
Key Improvements:
Dynamic Offset Approach: Instead of setting a fixed fake date, the script now calculates a time difference between the fake date and the real current time. This makes the fake date advance naturally as time passes.
Better No-Args Constructor: The no-args constructor now returns the current time plus the offset, which better simulates real date behavior.
Symbol Support: Added support for Symbol.species which helps with inheritance in modern JavaScript.
Performance.timeOrigin: Added handling for the timeOrigin property of the performance API.
Proper Date Output in Log: Using toISOString() in the console log for clearer date representation.
