Well, we don't use OSPF (we're an IS-IS house), and I have 
no experience with it on IOS XR.

But according to this link below, IOS XR 4.2 for the ASR9000 
requires the 'hello-interval' OSPF command to specifiy the 
value in seconds:

http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.2/routing/command/reference/b_routing_cr42asr9k_chapter_0100.html#wp187107531


But I've also just checked a Cisco 7201 router running 
12.2(33)SRE5, and it seems to have the value in seconds 
also:

lab(config-if)#ip ospf hello-interval ?
  <1-65535>  Seconds

lab(config-if)#


Are you sure you're referring to the Hello Intervals? I know 
millisecond values for OSPF timers would be possible for LSA 
calculations, and this applies to both IOS and IOS XR.

Cheers,

Mark.
