Initial Condition - Op Amp Comparator

A quick power cycle currently breaks my circuit. I am attempting to delay the initial triggering on startup of this comparator circuit. I have a timing cap that holds charge and is discharged down to ~0.4V when the circuit is turned off (Then slowly bleeds to 0V). A bleeder resistor in parallel with the cap either wouldn't discharge the cap fast enough to work or would be too low of resistance and ruin the timing circuit. Is there any way to either slow the triggering of comparator, increase the initial value on the negative rail, or decrease the value on the positive rail to 0 on turn off?
