UIC option in SPICE?

    I have read all I could find about the Use Initial Conditions (UIC)
    option in SPICE, but I still don't fully understand it. The reason I
    am confused is this: When I run a DC transient analysis with UIC
    enabled on a simple RLC tank circuit (with all passives having an IC of
    '0'), shouldn't these results be the same as a DC transient
    simulation with *no* UIC, since they should both have a initial
    starting condition of 0V/0A? Yet with the simulation with no UIC
    enabled, the circuit reaches steady state instantly; while with the UIC
    option enabled it takes a finite time to reach its voltage level, then
    over/undershoots a few time (rings) -- as it should. What am I missing
    here?

    Thank You,

    -Bill
