Couva, Trinidad and Tobago keeps America/Port_of_Spain time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Couva's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Couva and shifts a little each day. Couva runs 9 hours 30 minutes behind India, so a timing copied from an Indian panchang is wrong here. The live panel on each page is recalculated daily for Couva.
The live panel shows today's tithi, nakshatra, yoga, karana and vaara for Couva, updated daily.
The Panchang depends on local sunrise, and Couva's sunrise differs, so its tithi/nakshatra timings are specific to Couva.
