I did something similar in SuiteQL - a quick adaptation to a saved search seems to be working. Add a Date Created filter for the last two weeks and then a separate filter on Formula (Text) = T where the formula is:
CASE WHEN TO_CHAR({datecreated}, 'HH24MISS') > '150000' AND TO_CHAR({datecreated}, 'HH24MISS') < '160000' THEN 'T' ELSE 'F' END
