Not exactly: it provides mirrors that were (approximately?) up-to-date the
last time it checked, but the mirrors might be out-of-date or inconsistent
now.

30 minutes by default, at least up through FC6.
It really helps for yum, when using a new mirror, to first check the small
repomd file before downloading a large file. I do this in my stablemirror
yum plugin, so I know it helps (FC5 and FC6, not yet available for F7 as I
haven't gotten around to installing F7 yet). The checksums still won't
match, but it's much faster and uses less bandwidth.
