Thank you for your answer Veronica,
in the meantime I found an addons that does exactly what I need: sample
a strds at specific point in space and time defined by means of a point
vector layer having an attribute column with dates (tool prepared by
@Luca Delucchi: thank you)
I put the link here for anyone that in the future may have a similar
problem:

thank you again

Hello Ivan,
Space-time datasets in GRASS are map based, so, you either need to
create one vector map per date and then create the time series and
register the maps there, or in the case of STVDS, you could also add a
different layer per date to the same vector map and register those as
in:

(see the "Register a vector map with layers representing time steps"
example)
HTH,

Dear GRASS users,
I have a question about the creation of a spatio-temporal vector
datasets
I have a vector points map representing sample sites and it
includes a
field of the attribute table describing the sampling date (a
different
day, not sequential, for each point).
I would like to transform the vector point map into a stvds in
order to
use it with t.vect.what.strds.
My question is: is it possible to register the vector point map as
a stvds?
thank you
Ivan
