How to set the timezone on the Pico

It's not entirely surprising that the minute parameter doesn't respond well to out of range minutes. I'm extremely surprised it works on desktop!

However I've just tweaked Date so new 'cutting edge' - and 2v02+ builds - will have the change in.

To do stuff like alter the hour what I'd suggest is to:

• Create the date
  
• use var ms = d.getTime(); to get the milliseconds since 1970: http://www.espruino.com/Reference#l_Date_getTime
  
• Tweak ms however you want
  
• Use d = new Date(ms) to rebuild the date
  
  

Either that or you could keep changing E.setTimeZone depending on how you want the date to appear, which seems to be basically what you're doing?

I'm actually kind of surprised there's nothing standard in the Date class that allows you to change the timezone on a per-date basis, but it seems not!
