The libddccontrol library is, to my knowledge, only used by packages generated by the same source package, namely ddccontrol and gddccontrol. And time_t is only used internally, not exposed via the library's ABI. Under these circumstances, I don't think transitioning libddccontrol is, technically speaking, actually necessary.
