QuartzDB explicitly stores everything in UTC, in order to have control over the date-based sharding and retrieval. If you're reading the files directly you'll need to account for this. The API it provides will take timezones into account, so for example you can use the query method and pass in a local timestamp that includes a timezone offset and you'll get back the right results. I strongly recommend not reading the storage files directly and instead using the API that QuartzDB provides.
