Show HN: DateTime Utilities

I built this tool to replace all other web based ad-laden tools I use to work with timestamps in my day job. All of these things exist on the web already, but I put them all in one place and built a workflow around them to make working with them easier.

- It takes natural language input (yesterday at 3pm)

- It can convert a timestamp into different timezones

- It can convert a timestamp into various formats (how many of us have looked up "epoch converter" on google?)

- It can calculate the time difference between two timestamps

- It can add or subtract a time duration to a given timestamp

- It can round a given timestamp to the nearest minute, hour, day, month, year, etc.

I also added a few QoL features

- History section that stores the results on your browser

- A button to copy a result in the history to input (Copy to Input). This allows you to chain multiple operations together

- Last used timezones and formats will persist on your browser across sessions to make common conversions quick and easy

Here's a demo video to show how it all works: https://www.youtube.com/watch?v=pcBwIcqBLk8

I apologize for the potato video quality. I used free trial software and this was the first time for me to record or edit anything.

Happy to take questions and feedback!
