I don't really care when we do daylight savings in my day to day life. In my work life, however, I really do.
If it's not broken, don't mess with it.
Unfortunately, South Australia (where our servers are) decided to move the standard end date of daylight savings time by a week. Just for this year as far as I know.
This was not very well publicised here. Nor did it enable business to get their systems up to date.
This now means our server's PHP is broken, mysql is upset, PEAR::Date is upset and it has to stay that way for a week.
What a %#^#%ing mess.
