In my first 5 blogs on Temporal, I failed to note something pretty important about their usage. The start and end times for the row (and it follows, the historical rows) are likely not in your local time zone. They are stored in UTC time zone. This is obviously good because of that pesky daylight saving time issue where 1:30 AM occurs twice each year (here in the US, the time occurs on the first Sunday of November).
Unless you live in London, England or someplace where the offset from UTC is 0, it can make working with these tables confusing, because most people rarely work in UTC time, and even rarer is to think in UTC time when most of your data is likely in your local time zone. So you write your query and use local time…and then, most likely, data is returned…but not necessarily the data you actually desired.
