A Unix timestamp converter that includes the micro and nanoseconds▲27
I find myself having to convert a lot of unix timestamps to a human readable format, but most of the online calculators I found don't include the micro or nanoseconds in the human readable output. It's a small detail, but I find myself having to manually space out the timestamp frequently. I'm learning frontend development, so I made this converter to hopefully make it easier to convert timestamps. Welcome to any feedback :)
