Are Unix timestamps measured in seconds or milliseconds?
Both forms are common. This tool supports each unit and shows the interpreted value so you can confirm the conversion.
Why are UTC and local times different?
They represent the same instant in different time zones. Local output follows the time-zone settings of your browser.
Does converting a date send it anywhere?
No. Date parsing and conversion use browser APIs locally and do not upload your value.
