Implemented Qartod Timing/Gap Test

[Sakshamgupta90]

Implemented Timing/Gap Test as part of the IOOS QARTOD quality control checks.

Timing/Gap Test checks for the arrival of the data, ensuring that the data is arrives within the expected time window and flags cases where the data is either delayed or missing.

Code Description

The logic for the test calculates the difference between the current time now and the timestamp of the latest data tim_stmp. If this difference exceeds the expected increment tim_inc, the data is flagged as Fail.

• A function timing_gap_test that takes the timestamp of the most recent data tim_stmp, the expected time increment tim_inc, and checks if the data has been received within the expected interval.
• The function will return:
  • Pass (1) if the data is within the expected window.
  • Fail (4) if the data arrives later than expected.
• Unittest were written covering following scenarios:
  • Data within the time window (expected result: pass).
  • Data outside the time window (expected result: fail).
