spitfire on 12:26 AM 11/24/2025: Very cool challenge! The password is “admin”, but the time has to be 2024-11-22 12:00:00 with nanosecond 123456789. At first, I tried changing my computer’s clock and running a loop to brute-force it, but that felt too much. Then I tried setting the exact time using date, but my system clock didn’t stay frozen. That’s when I remembered the simpler solution: creating a library to override the time calls in your program. It’s a technique I already knew, but it didn’t come to mind right away. That’s why these challenges are great for keeping the mind sharp. Thanks.

spitfire on 5:00 PM 11/24/2025: Buffer overflow? It's cool too.
