    Fix uninitialized variable bug in KEYRING ccache
    
    Commit 5f4a4d7d357fedac5feadc65c09ecf487ff98db8 removed the only
    unconditional assignment of ret in get_time_offsets, causing the
    function to return an uninitialized value if nothing goes wrong.
    Initialize ret at declaration time to fix this.
