But this has no effect on whether transmit time stamps are enabled.

The timer work must run whenever the (physical) clock is
running. Otherwise you will have discontinuities in your PTP clock.
The kernel must always behave correctly, regardless of what user space

When the user calls clock_gettime(), the result must always be
consistent. This has nothing to do with time stamping at all.
