I've seen a few questions on this site confirming that the mitzvah for wearing tefillin is during the entire day. Indeed, on Tish'a B'Av tefillin is not worn in the morning for Shacharit but for Mincha.
However, while I haven't seen anyone wearing tefillin at night, if one did, would he fulfil the requirement of wearing tefillin for that day? If not, what is the source / support that tefillin can be worn only during daylight hours, and when does the permissible time end?
