Uniform Timezone Extension

Converts and decodes, where possible, complete upload/post date-time values into standard timezones (like UTC or your machine's local timezone) and allows the conversion to any other timezone, besides exporting/copying all values. See https://github.com/bellingcat/uniform-timezone for supported platforms, but it works for many social media platforms + their Wayback Machine archives.
