Hello Sir,
I found these following cases where it still fails to detect correct overlap

While testing I found following solutions for few cases:

1. Sorting of these time logs list based on from_time

2. replacing “and get_datetime(next_row.from_time) <= get_datetime(row.to_time)" with "and get_datetime(next_row.from_time) < get_datetime(row.to_time)"

3. replacing “get_datetime(next_row.to_time) >= get_datetime(row.from_time)" with "get_datetime(next_row.to_time) > get_datetime(row.from_time)"
   After doing above three steps ,still this fails with last case as last case has 2 sets of overlapping job cards with 2job cards in each
