Iain will be missed. It was only last November that he gave up some time to present a talk on DateTime at the melbourne.au PM.
Iain talked in detail how the development was proceeding on the Datetime modules and how he spent the last 8 months hard work crafting
hacking ("hacking" is a poor choice of words. Conceptually DateTime is not for the weak of mind). The talk was well presented, informative and most of all amusing (especially the bit on the evolution of the French Revolutionary Calander)
I will certainly be thinking of him when I'm using any of his modules. His legacy is more than mere code.
