The documentation was missing a mention of the `time` parameter in the following TypeScript functions: * `Rotation_ECT_EQD` * `Rotation_EQD_ECT` Likewise, the `time` parameter was not documented in the corresponding Kotlin functions: * `rotationEctEqd` * `rotationEqdEct` These mistakes have been corrected.

# rotationEqdEct
|
|
|
|
fun [rotationEqdEct](rotation-eqd-ect.md)(time: [Time](-time/index.md)): [RotationMatrix](-rotation-matrix/index.md)
|
|
|
|
Calculates a rotation matrix from equator of date (EQD) to true ecliptic of date (ECT).
|
|
|
|
This is one of the family of functions that returns a rotation matrix for converting from one orientation to another. Source: EQD = equator of date Target: ECT = true ecliptic of date
|
|
|
|
#### Return
|
|
|
|
A rotation matrix that converts EQD to ECT.
|
|
|
|
## Parameters
|
|
|
|
| | |
|
|
|---|---|
|
|
| time | The date and time of the equator/ecliptic conversion. |
