The sidereal day is the (mean) time between two transits of the R.A. origin, i.e. the vernal equinox. You are right, and this is strictly not equal to the time it takes the Earth to do a rotation in relation to the fixed stars, because the Vernal Equinox itself is precessing (and nutating).. The amount of time it takes the Vernal Equinox to do a full rotation is suposed to be well known (26000 ...

Solar time - Wikipedia

en.wikipedia.org/wiki/Solar_day

calculation of elapsed time by the apparent position of the sun On a prograde planet like the Earth, the sidereal day is shorter than the solar day. At time 1, the Sun and a certain distant star are both overhead. At time 2, the planet has rotated 360° and the distant star is overhead again (1→2 = one sidereal day). But it is not until a little later, at time 3, that the Sun is overhead ...

The difference between the mean sidereal day and mean solar day can be derived approximately as follows: As in a Solar Tropic year [footnotes 1], the mean solar time delayed 1 day respect to the mean sidereal time, thence: [math] \frac{24^h}{365.2422}\simeq 3^m56^s \qquad \mbox{(1)} [/math] Thence, a sidereal day is shorter than the solar day for about [math]3^m56[/math].
