Ephemeris Time and TDB conversion to other time systems is wrong by 100 years

`1798-07-04T12:00:00 ET (-3169195200)` and `1953-10-09T12:00:00 ET (1696852800)` should be `CAL-ET 1899 JUL 29 00:00:00.000` and `CAL-ET 2053 OCT 09 00:00:00.000`

Hifitime references all epochs from J1900. SPICE however reference them from J2000. This leads to potential confusion when initializing epochs if someone only has data from SPICE. This issue should...

Optionally allow Chronos conversions

This is helpful to support human-time which isn't UTC.

Allow to ignore leap seconds after a given date

This is important as some simulation systems might not include all of the leap seconds. This is needed for validation of astrodynamics computations.

Goenv from working directory does not add pwd to GOPATH

1

If one's working directory contains `src`, `pkg` and `bin`, then activating the environment won't correctly set the `$GOPATH`. The solution I found was to edit `goenv/activate` and change the beginning...

Hi there! Thanks for publishing and maintaining this cool crate! I'm still testing it out but so far, it looks fantastic. I was wondering if there was any interest in...

SOFA provides support for TCB: this could be useful but I'm not sure if there would be that many uses of it. - TCG to TT: https://github.com/Starlink/sofa/blob/master/src/tcgtt.c - TCB to...

Reopening the work on #237 . @gwbres I was not able to push to your fork of the repo anymore, so I've pushed a new branch. I think you have...

Display should print in Gregorian in the Epoch's time scale

3

At the moment, `fmt::Display` of an `Epoch` will print it in UTC. Only the `fmt::Debug` prints it with the current time scale. This is needlessly confusing. For example, in Nyx,...

J1900 and J2000 references mix up, causing older Julian dates to be wrong

1

Internally, there is a mix up between the J1900 reference and the J2000 reference. Specifically, the `J2000_TO_J1900_DURATION` constant is a duration of `36524 days 12 h` but it should be...
