Frog,
There is no relationship between the hello interval & the accurancy of the
router's clock/time.
Once adjacencies are formed, each router expect hellos every 10/30 seconds
interval depending on your topology or any value you set the hello to. Each
router will understand & be patient if the hellos do not arrive at the
interval agreed on, but they tend to run out of patient once the dead
interval in up (ie 40 or 120 seconds or whatsoever value you manually
choose).
If R1's clock is 21:10:01, January 29, 1917 & R2's clock is 10:48:37, July
02, 2006; they both will exchange hello packets at the regular interval
manually configured on their interface or imposed by their OSPF interface
type, regardless of the fact that, their time/clock are ages apart.
