If you are interested in astronomical time scales, the next version of Lady Heather can display time in most of those (plus a few others like Besselian and HJD). It also supports importing the current delta-T value from an external file (that something like a chron task can keep updated from your favorite source) or you can set it manually from the keyboard/command line. ------------------- > but also TAI, UT, UT0, UT1, UT2, ET, TDT, TDB, > TT, TCG, TCB, GPS, etc...

Displaying the tie is not good enough for most practical uses. You need to TRANSFER the time very accurately. A display is only good for transferring the time to a human brain via a pair of eyeballs. People want to do things like aim a telescope or track a satellite. So I might need to run a control loop at 10Hz to control a servo motor but with "Hz" based on a sidereal second. The problem to be solved is to enable people (or more likely machines) to synchronize their actions over large distances but using a time "flavor" different from UTC. I think the test case to see if any proposed solution "works" is to try and time stamp a data stream across a leap second event.
