Extracting the actual date of a LinkedIn Post

from datetime import datetime


def extract_unix_timestamp(post_id):
    # BigInt needed as we need to treat post_id as 64 bit decimal.
    # Python uses arbitrary-precision integers, so no need for explicit BigInt.
    as_binary = bin(int(post_id))[2:]
    first_41_chars = as_binary[:41]
    timestamp = int(first_41_chars, 2) / 1000

    # Convert Unix timestamp to a readable format
    readable_timestamp = datetime.utcfromtimestamp(timestamp).strftime('%Y-%m-%d %H:%M:%S')
    return timestamp, readable_timestamp

# Example usage:
post_id = 7089460991175901184
timestamp, readable_timestamp = extract_unix_timestamp(post_id)
print(f"Unix Timestamp: {timestamp}")
print(f"Readable Timestamp: {readable_timestamp}")
