Issue: Invalid `date-time` and `time` Formats Accepted

[SharathPrakash]

I am encountering issues with the JSON Schema validation for both the date-time and time formats. The validator is incorrectly accepting invalid strings that should be rejected according to the ISO 8601 standard.

1. Invalid date-time Format:

The following date-time string is being accepted as valid, but it should be considered invalid:

• Valid date-time: 2024-06-01T12:34:56Z
• Invalid date-time (but accepted): 2024-06-01T12:34:56ZAS

The ZAS suffix is not part of the correct ISO 8601 format, yet the validator allows it.

2. Invalid time Format (with Offset):

The following time string with an offset is accepted as valid, which is correct:

• Valid time with offset: 12:34:56+12:44

However, the following string is also accepted, which should not be valid:

• Invalid time with extraneous characters: 12:34:56+12:44AS

The AS suffix is not part of the valid ISO 8601 time format with offset, but the validator incorrectly allows it.

Expected Behavior:

1. For the date-time format, only valid ISO 8601 date-time strings (e.g., 2024-06-01T12:34:56Z) should be accepted, and any additional suffixes (like ZAS) should be rejected.
2. For the time format with offset, only valid time strings with an offset (e.g., 12:34:56+12:44) should be accepted. Any extra characters (like AS in 12:34:56+12:44AS) should cause the string to fail validation.

Steps to Reproduce:

1. Use a JSON Schema validator that supports the date-time and time formats (e.g., AJV, Joi, etc.).
2. Provide the following strings as input:
   • 2024-06-01T12:34:56ZAS for date-time.
   • 12:34:56+12:44AS for time with offset.
3. Both strings should be rejected, but the validator accepts them as valid.

Version of the Validator:

• Version: 1.4.0

Additional Notes:

• The issue arises when extra characters are appended to valid time strings, which should be rejected.
• This behavior could be problematic when ensuring strict ISO 8601 conformance for both date-time and time fields with offsets.

Thanks for investigating this!
