A Rust-based timer application that implements a time-based execution control mechanism. This project demonstrates how to create a program that checks the time elapsed since compilation and executes specific actions based on a predefined time threshold.

Downlaod Timer PoC : Downlaod

• Tracks time elapsed since program compilation
• Implements a configurable time threshold (default: 1 day)
• Provides countdown information until the target time
• Exits with a specific status code when the time threshold is reached

The program uses:

• chrono crate for datetime handling
• Build-time environment variables to capture compilation timestamp
• Time difference calculation between current time and build time

• Rust (latest stable version)
• Cargo (comes with Rust)

To build the project:

cargo build

To run the project:

cargo run

1. The program captures the build time during compilation using environment variables
2. When executed, it calculates the time difference between the current time and build time
3. If the elapsed time exceeds the configured threshold (1 day by default):
   • Prints "Time of attack!"
   • Exits with status code -1
4. If the threshold hasn't been reached:
   • Displays the remaining time until the threshold

The time threshold can be modified by changing the TIME_ATTACK_IN_DAYS constant in src/main.rs.

Found the idea while discussion. The author did not known !.
