Convert seconds to TIME value with overflow checking
SYNOPSIS:
sec_to_time()
seconds number of seconds
unsigned_flag 1, if 'seconds' is unsigned, 0, otherwise
ltime output TIME value
DESCRIPTION
If the 'seconds' argument is inside TIME data range, convert it to a
corresponding value.
Otherwise, truncate the resulting value to the nearest endpoint, and
produce a warning message.
RETURN
1 if the value was truncated during conversion
0 otherwise
