The ‘type’ of ‘expires’ column in location
table is ‘datetime’ whereas in table presentity the type is
‘int’. Is there any reason behind this?
I hope for the sake of uniformity ‘expires’
can be changed to ‘datetime’.
it was developer choice for each module, the one being 'int' is
storing the unixtimestamp which is actually easier to use inside the
code, because it does not need conversion, not timezone adjustments.
usrloc (using location) is one of the very old modules, whereas
presence was developed many year after it.
