Just to add a little hint, try using help:

IDL>help, STRING(year)
<Expression> STRING = ' 2011'

Now, you can clearly see the blanks.

And yes, "+" is doing concatenation:
IDL> help, string(year) + string(mon) + string(day)
<Expression> STRING = ' 2011 10 21'

A piece of advice, since you're starting out: be careful with "print". Sometimes, you think something has gone terribly wrong, when in fact everything's OK:
IDL> a = 14.12345
IDL> print, a
14.1235

Did IDL truncate my number? No, it's just a limitation of the default print format:
IDL> print, a, FORMAT='(F10.6)'
14.123450
