British Hindu calendars often reprint IST tables. That puts Brahma Muhurat before 1am GMT in winter and mis-times temple abhishek. London, Birmingham, Leicester and Manchester pages use Europe/London, so BST in late March–October is already in the sunrise and Rahu Kalam figures.
The UK switches to British Summer Time on the last Sunday of March and returns to GMT on the last Sunday of October. Temple notices that quote 'sunrise 6:12' without naming BST/GMT are a common source of one-hour errors around those weekends.
