To change the time format

1. A time format must contain an Hours tile.
2. In a time format, you can use either the character, 'Z ' or any one of the T.zone tiles.
3. You can choose only one format from the Hours, Mins, and Sec tiles.

4. You can apply this transform to multiple Time columns using the  icon against Columns to apply.

1. Using the logical operators, you can combine the conditions and apply logic to determine the rule of precedence. The final expression is displayed in the Criteria expression box. You can click Edit to alter the default expression using logical operators and parenthesis to specify the precedence or the sequential order as to which condition should be evaluated first. Click Save after making the required changes. 
   

1. For example, In the expression, ((1 OR 2) AND (3 OR 4)) , at first the condition ( 1 OR 2 ) will be executed and the condition ( 3 OR 4 ) will be executed next. Thirdly, since, the AND operator is used, the filter will be applied when both the conditions are true.

For example, in the above screenshot, the Data quality option is selected for the All columns filter in the Filters section. Based on the selection, further options to filter specific values are displayed in the All columns (Data quality) section.

6. You can choose to include or exclude the selected items in the last section.

7. If you want to remove all the filters for some reason, you can use the Clear button.

8. A live preview of the filter transform is shown as you make changes. 

9. Click the Apply button to apply the transform along with the filters.
