"""Validates if the input time string matches the 'HH:MM:SS' format.

The function checks if the input string adheres to the 24-hour time format, where:
- HH (hours) ranges from 00 to 23,
- MM (minutes) ranges from 00 to 59,
- SS (seconds) ranges from 00 to 59.

If the input string matches the format, it is returned as is. Otherwise, a ValueError is raised with details about the expected format and the invalid input.

Args:
    time (str): A string representing the time in 'HH:MM:SS' format.

Returns:
    str: The input time string if it matches the expected format.

Raises:
    ValueError: If the input string does not match the 'HH:MM:SS' format.
