I have a process that starts on a timer. But it doesn't always start. It&#

If the timer is in a Start Event you will need to republish the model every time you change the constant.

You need this because when you configure the timer the model creates an image with the values at design time (7:30AM in this case) to record what values it will use to launch process instances. When you update the constant at runtime the model already has an image of the original values because you configured the timer at design time, that's why republishing is necessary. This is by design but can be easily worked around by the approach described above if the update of the constant is frequent.
