The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified

• sceFiosDateFromComponents, sceFiosDateGetCurrent, sceFiosDateToComponents and sceFiosIsValidHandle (libSceFios2) - the date packing and the handle validity rule are unverified and the declarations in Export.cpp still carry no parameters. kalaposfos13/fios2 (src/fios2.h, PS4) and RPCS3 (Emu/PSP2/Modules/sceFios.cpp) independently declare sceFiosDateFromComponents(tm*) and sceFiosDateGetCurrent() returning a 64-bit date, sceFiosDateToComponents(int64_t, tm*) returning the tm pointer and sceFiosIsValidHandle(int) returning a bool, but both may descend from one leaked Vita SDK and kalaposfos13's bodies are guesses (mktime times 1e9). sonny-tel/libSceFios2 (a header read from a Fortnite build) also declares sceFiosIsValidHandle(int) and gives SceFiosParams, SceFiosOpAttr, SceFiosOpenParams and SceFiosStat layouts, unverified against firmware
