Continuous equates to "start automatically when sql server agent starts".
However you can't start continuous and stop it within a time boundary - at
least not easily. The simplest way to achieve this is to hacve a continuous
merge agent job which is disabled, and have another job which runs on a
schedule which enables the first job and starts is, then have a third job
which stops and disables the merge agent job.
