- Comment/Request
- I love the simplicity and it would really be a useful tool for me, but I needed Earth's longitude. It would also really help out if the reverse search could be done, entering the coordinate and getting the date as an output, since what I was searching for is the exact day and time Earth's longitude reached 135°.
