Does timers play any role in neighbor relationship in EIGRP?
Play the same with OSPF. It will definitely be down.

Subject: Hello Timers Mismatch
Hello,
I have connected 2 routers R1 and R2 using 2 serial links. I changed
the default value of hello timers and hold timers in one of the
interface only at R1 router. I thought neighborship will be down due to
timers mismatch, but still it is up in both the interfaces.
R1;
interface Serial1/0
ip address 155.1.0.5 255.255.255.0
ip hello-interval eigrp 100 3
ip hold-time eigrp 100 9
encapsulation frame-relay
frame-relay map ip 155.1.0.4 405 broadcast no frame-relay inverse-arp
end
interface Serial1/2
ip address 155.1.45.5 255.255.255.0
router eigrp 100
network 155.1.0.5 0.0.0.0
network 155.1.45.5 0.0.0.0
network 155.2.0.5 0.0.0.0
no auto-summary
R2:
interface Serial1/0
ip address 155.1.0.4 255.255.255.0
encapsulation frame-relay
frame-relay map ip 155.1.0.5 504 broadcast no frame-relay inverse-arp
end
interface Serial1/2
ip address 155.1.45.4 255.255.255.0
router eigrp 100

Could you please explain why the neighborship is up on the mismatched
interface.
Thanks,
