The time_t type is part of the user interface and not always the same, with the move to 64-bit timestamps and the difference between architectures.
Make the quota format definition independent of this type and use a basic type of the same length. Make it unsigned in the process to keep the v1 format working until year 2106 instead of 2038 on 32-bit architectures.
Hopefully, everybody has already moved to a newer format long ago (v2 was introduced with linux-2.4), but it's hard to be sure.
