what's simplest way of programming daylight savings?

[hahher]

because you can't just say go back 1 hour or else time would be stuck, so what would be the simplest and most efficient way of doing this?

 

[MrScott81]

in what, a program?

boolean alreadyChanged=false;
...
if(isDaylightSavingsTime)
{
//need to set back time
if(! alreadyChanged)
{
setTimeHere();
alreadyChanged=true;
}
}

Why don't you use a year variable.

Set some kind of flag.

Yes, as in scottdog81's example. Is the term 'flag' obsolete?

in wrist watch i guess.

i'm not programmer. but was just curious. wondering about factors like being most efficient to save space, and also not get screwed up if watch gets reset/battery gets replaced.
