When adjusting picture times, the offset in seconds is stored in a 32-bit int. Make it a 64-bit int. Sounds crazy, because why would you want to move the pictures by more than 70 years? Well, suppose it is the year 2039, for some strange reason your camera was set to unix epoch and you want to adjust the pictures to current time. Ok - that's a far-fetched scenario. The real reason is that this hopefully silences a Coverity warning and avoids integer casting. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
