Timezone / Locale setting
When viewing US region, you may want time relative to the US. When viewing EU region, you may want time relative to EU
For example, checking why my mail isn't sending at 8PM GMT+2, then looking at the logs that have a time of 2PM GMT-4 makes debugging slightly more annoying than it should be.
It would be great to be able to manually set the Timezone / Local for log files or other data exports
