Glulx timekeeping in Git

I’m running Git on a linux server, and see that there is apparently no “glulx timekeeping” support. Is this perhaps because cheapglk does not support real-time events? If so, will recompiling using glkterm instead help? (I’m asking rather than just trying because I don’t have write access to the directory where Git is…)

Checking the source code for the two, this appears to be the case.

Correct on all counts.
