[R-Forge #2750] Logical operators drop tzone index attribute

This is because the .xts constructor doesn't pick up the tzone attribute on the index if the tzone argument is missing.

> x <- xts(1:10,Sys.Date()+1:10)
> attributes(.index(x))
$tzone
[1] 'UTC'

$tclass
[1] 'Date'

> attributes(.index(x>1))
$tzone
[1] ''

$tclass
[1] 'Date'
