Daylight Saving Time

[jasonluckett]

Hi all,

Can anyone help with the above in max? I am currently doing a sun study near Dublin, Ireland and wish to accurately show the sun's position and shadow casting of the proposed development. The control within the daylight system is at best confusing.

I know this sounds obvious but I take it one has to manually turn on or off the Daylight Saving Time tick box for the appropriate time of the year? This is probably like this as the date falls on a different date each year (ie. the last Sunday in March and October)? ie sun 26th march 2006 and sun 25th march 2007 and so on). Surely this would of been programmed into Max based on country preferences so as to avoid this manual user adjustment?

This unfortunately doesn't seem to be keyable so one couldn't actualy create a correct animated sun study (correctly adjusting to DST when needed), the only way this seems possible is to ignore DST and use Time Zone (to act as DST) which is keyable?

Sorry for the above being long winded but is a little tricky to describe!

Thanks in advance,

Jason

Hello Jason,

 

Maybe I'm totally wrong, but I think the DST is simply the option that changes the hour (you know, when you lose that hour of sleep around April)and then changes it again when automn comes (then you can sleep one hour longer!!). That's all... If the country for which you're doing the study doesn't use DST, then don't use the option (I think only countries around the equator and Japan do not use DST...)

so to sum up, you don't have to animate this.

 

I hope I wasn't too confusing...

 

Cheers,

Matt

Thanks for quick reply Matthieu,

 

I've sorted it out the DST in Max does not follow local rules (ie sun position is not linked into country settings such as Ireland it's just a general setting... a little poor in my opinion as it wouldn't take much to incorporate), so one has to do manually.
