We’ve been using the last update to sort studies based on the order in which they have received their last instance. This is useful for us, since users save their progress in our application in Dicom, so the study with the most recent additio is almost always the last study you have seen.
We also display this time, to provide some feedback to users.
However, we recently noticed that this time is not always the system time. Is there a setting we should be aware of to control this timezone? Or is it always a specific time zone?
If UTC time is not user-friendly enough for your end users, you can easily convert it to your local time in a higher-level application written in any computer language.
