How do I check for DST?

[Boofo]

Can someone please tell me why this doesn't work and how to fix it?

if (!$post['dstonoff']) {
$post['tzoffset']--;
}else{
// DST is on, add an hour
$post['tzoffset']++;
}

It seems it wants to grab whatever I am checking for first and not go any further. I always have to change this whenever DST goes off or on. ;)

Nobody can help me with this? ;)

[Boofo]

I'll try one more time asking for help. ;)

The wy vB does it is via a test in Javascript at the bottom of the page, and if th etest is true, it runs a cron which updates the user profile (I think?) - it's not by any means a simple thing...

The code above works if you only use one of them. Then it works right. But if you try to "else" them, then it only picks the first one, no matter which one it is. How can I get it to work with "else"?

Is dstonoff a TRUE/FALSE item? the only way that (!$post['dstonoff']) would never return the first (or second) clause is if $post['dstonoff'] is never FALSE (or TRUE)...

All I know for sure is that whichever one I put first always works. How would I check for it then? ;)

tryif ($post['dstonoff']===TRUE)
{ // DST is on, add an hour
$post['tzoffset']++;
}
else
{
$post['tzoffset']--;
}

[Boofo]

tryif ($post['dstonoff']===TRUE)
{ // DST is on, add an hour
$post['tzoffset']++;
}
else
{
$post['tzoffset']--;
} I'll try this and let you know. ;)

Should there be 3 equal signs?

[Natch]

Yeah: it's a more exact test...

[Boofo]

So, this would work, too then?if ($post['dstonoff']===FALSE)
{ // DST is off, subtract an hour
$post['tzoffset']--;
}
else
{ // DST is on, add an hour
$post['tzoffset']++;
}

Should do mate

I think I fixed it. Here's what I have now and it seems to follow whatever you have your DST setting at in your User CP. ;)

$post['tzoffset'] = $post['timezoneoffset'];

if ($post['dstonoff'])
{
// DST is on, add an hour
$post['tzoffset']++;

if (substr($post['tzoffset'], 0, 1) != '-')
{
// recorrect so that it has + sign, if necessary
$post['tzoffset'] = '+' . $post['tzoffset'];
}
}

Good work mate: I knew you'd get it sorted ;)
