Editing SFS Files with Hyperbolic Orbits

[onewatt]

I'm editing an SFS file to recreate the orbit of 1I/ʻOumuamua in KSP and need some help with positing the asteroid in time.

Here is the orbit info:

ORBIT
{
    SMA = -9810152184.3379135
    ECC = 1.199340431517006
    INC = 122.6811009854535
    LPE = 241.6912942989328
    LAN = 341.59948540862757
    MNA = 45.352545166989543
    EPH = 2458005.9891368006
    REF = 0
}

I now EPH is the Ephoch of the orbit but I can't figure out how to move the asteroid back on it's orbit so that it's incoming to the Kerbal system, currently I have it leaving at a hight rate of travel ~11Km/s

I've run the UT clock forward ten years to get some room to work in, but setting the EPH down to 1 for e.g. doesn't move the object.

OK, looks like I got it: https://imgur.com/a/zSsBM
