Quick and very dirty time math
Raw
gistfile1.c
// get a time stamp from a pebble time struct
long timestampFromTime(PblTm time)
{
return (((time.tm_mday * 24) + time.tm_hour) * 60 + time.tm_min) * 60 + time.tm_sec;
}
long timeintervalBetweenTimes(PblTm time1, PblTm time0)
{
long timestamp1 = timestampFromTime(time1);
long timestamp0 = timestampFromTime(time0);
return timestamp0 - timestamp1;
}
