Harrow, England, United Kingdom keeps Europe/London time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Harrow's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Harrow and shifts a little each day. Harrow runs 4 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 Harrow.
The live panel shows today's tithi, nakshatra, yoga, karana and vaara for Harrow, updated daily.
The Panchang depends on local sunrise, and Harrow's sunrise differs, so its tithi/nakshatra timings are specific to Harrow.
