I'm trying to figure out how to calculate Coordinated Mars Time (MTC). Can it be calculated directly from Earths current time/date, or calculated from the current Mars Sol Date (MSD)?

From [this wiki page](https://en.wikipedia.org/wiki/Timekeeping_on_Mars) I can calculate the current Mars Sol Date using:

> 
> MSD = (Julian Date using International Atomic Time - 2451549.5 + k)/1.02749125 + 44796.0, where k is a small correction of approximately 0.00014 d (or 12 s)

but how would one calculate Coordinated Mars Time?
