true in general. In this case the warning exists because seconds_to_next
is an int while now is time_t which might be unsigned int, or whatever -
but on a 32-bit system both int and time_t are 32-bit, thus even when
time_t is 64-bit on a 64-bit system we can cast to int until year 2038,
after that date we might consider something better ... :)

GŁn.
