Hi David,

https://sourceforge.net/p/testlilyissues/issues/3830/

says:
"
The \offset function introduced in 2.17.95 (see
Issue 3629 for details) merits full documentation.

Unfortunately it does not easily 'slot in' to any
existing section in either the LM or NR.  Perhaps
the most obvious place for it is Section 4.6.1 in
the LM, "Moving Objects", but even here some
rearrangement of the existing text would be needed.
If it were to be added to the LM in this way, the
existing documentation in the NR (in A18 "Available
Music Functions") would just about suffice.
"

`offset' is in music-functions-init.ly
see there for the doc-string.

An example is in our regression-test look there for offsets.ly

Cheers,
