TimeStamp from Go project in Unix format gives year 9999

[Kenya-West]

Current behavior

When I put timestamp 1766835354039 to DevToys, it gives me year 9999 while all other times (day, month, hour, etc.) provide correct values.

How to reproduce it (as minimally and precisely as possible)

1. Copy 1766835354039 value
2. Paste in Timestamp tool

Expected behavior

It should display year 2025, like https://www.epochconverter.com/ does
