Well... the padlock means you have your iPhone locked in portrait mode. Double click your home button... it'll bring up the App switcher.. scroll to the left (finger swipe the switcher to the right) until you come to the lock... touch it to disable the "Landscape Lock." As far as you time and clock goes... is your iDevice Jailbroken? Could possibly be some type of clock tweak/package that's not meshing well w/ another JB tweak.
