[LON-CAPA-users] accessing timestamps in problems

[Flammer]

I am trying to access times when different parts of a problem were
correctly solved within that problem.  We have successfully accessed
information like if it has been solved by using

&EXT("user.resource.resource.partid.solved");

but I don't know the syntax for calling timestamps associated with when it
was solved.  I know the information is stored someplace because it can be
accessed when you grade a problem.  Could anyone tell me the format for
accessing time stamps in a problem?

Thanks.
