I just come across to work with an API related to timestamp and need to do some time unit conversion. Have tried to found some timestamp converter from the web and firefox addon, but none of converter I find suit my need. So just spend a day to create a converter with a calendar on it.
Features:
- Convert timestamp to date, click on the log to navigate the calendar
- Convert seconds / minutes into number of days, hours
- Arrow key to navigate the calendar (only when focus is not on the text field )
Screen cap of the timestamp converter
