After I wrote about this before, someone suggested a brilliant
workaround. Use "Run every", but with shorter time, and wrap your
code with a conditional check for whether it is time to run. I
haven't implemented this yet (still testing my system), but I can
think of two ways to do this.
One way is to check whether the current time is past the start time
but within the shorter time interval. There might be a risk of
missing a start time, however, if there is some delay longer than the
shorter time interval.
Another way is, using a static variable, remember the last time a run
was done, and if the current time is past the next start time, and the
previous run was before that, then it is time for another run. This
would be more reliable.
