Thanks. We are using sequencer-1.9.5 and it looks like this problem has
been fixed by this version. In seq-1.9.5, all the delays are relative to
sysClkRateGet(), so your conversion factor is no longer needed.

Note that this same problem does appear in some of the old device and
driver support which is included with base in 3.13. Other places in base
(3.13.7) where I have found taskDelay() using a constant include:

	ca/vxWorks_depen.c
	db/dbCa.c
	rec/recWaitCa.c
