Node-red-contrib-sun-position author

Looking for the author of this node to ask if it is possible to set the start-time and end-time programmatically in the within-time node. Combed his tutorials and played a bit with the node but haven't gotten a definitive answer to my question. Hoping they wander through this forum sometimes.
Thanks

Perhaps open an issue on github
