MC2500 Delayer: Being able to remember total "high" time

CRAFTBOOK-2585 - Reported by pmpmpm

Hello,

Actually the MC2500 Delayer immediately stops when input goes from high to low. What about adding somewhere an option (such as a "[:true]" on the third line) to make it remember how much time the IC was was powered on, and outputs high for the correct amount of time?

For example, with a delay of 10, if I stop the IC at t=11s, the IC outputs high until 10+11=21s.

Thanks for readng.
