[PD] triggering vline~ compared with line~

Hm, somehow I assumed that tabwrite~ would not be block-quantized, but
that it instead was time-accurate. Well,but if tabwrite~ records
block-aligned, then the behaviour of vline~ inside the patch is fully
correct. However somehow it frightens me, that setting the phase of a
phasor~ is not time-accurate, but block-aligned as well ...

It looks at the clock.

vline~ gets Pd's notion of "now" (its "logical time") using
clock_gettimesince() which gives the: "elapsed time in milliseconds
since the given system time" (m_sched.c)
