Applicability to time-trialing has everything to do with fork rake, if you're concerned about the
effect of wind on a deep-dish rim'd front wheel.
Time trial specific bikes typically use a 4.0 fork w/ a 73 deg or slacker head angle to achieve
trail numbers sufficiently high enough to aid in the stability of the front end in crosswinds. If
you can find a 3.8 offset fork, so much the better.
