datestamp [SOURCE FILE: ahr.c]

Generate a full date stamp (year, month, day, hour, minute, second, nanoseconds)

Code Explanation:

1. Header Files:

#include <stdio.h>: Includes standard input/output functions for printing the timestamp. #include <time.h>: Provides functions for accessing system time.

2. Function ahr():

Gets Current Time: clock_gettime(CLOCK_REALTIME, &currentTime): Retrieves a high-precision timestamp and stores it in the currentTime structure. Extracts Time Components: localtime_r(&currentTime.tv_sec, &timeInfo): Breaks down the timestamp into individual components like year, month, day, hour, minute, and second, storing them in the timeInfo structure. Formats and Prints Timestamp: printf("%04d%02d%02d%02d%02d%02d.%09ld\n", ...): Prints the timestamp in the specified format: YYYYMMDDHHmmSS.nnnnnnnnn (year, month, day, hour, minute, second, nanoseconds)

3. Function main():

Calls ahr(): Executes the ahr() function to generate and print the timestamp.

Setup Instructions:

a. Create Directory:

• Open a terminal and execute: mkdir /home//uCode (Replace with your actual username).

b. Write Code: Navigate to the directory: cd /home//uCode

• Open a text editor like nano: nano ahr.c
• Paste the provided code into the file.
• Save the file (usually Ctrl+O in nano, then Ctrl+X to exit).

c. Compile:

• In the terminal, run: gcc -o ahr ahr.c

d. Run: Execute the compiled program: ./ahr

It will print the generated timestamp in the specified format.
