Hi Everyone,

I'm here for asking how to i reset the time?  
Examples: when i inject a timestamp from 8 a.m to 5 p.m and the debug will give me Singapore time and the date.

When after 5 p.m will auto reset the time, will be continuously for the next day.

Thanks

Hi Kelvin, not sure I really understand your issue. Could you post some screen-shots to illustrate it?

Node-RED simply uses the underlying OS time settings so you should check those too.

It seems to me what he wants is a window of 8am to 5pm when data will be sent or time is sent? I'll be interested in seeing the answer to @Colin questiom.

I am sorry, that sentence does not make sense. I presume that the problem is that English is not your first language. Please try and explain in a lot more detail what you want to do. Perhaps then we can understand.  
Also tell us what your first language is, perhaps someone here understands it.

Perhaps a [node-red-contrib-simple-gate](https://flows.nodered.org/node/node-red-contrib-simple-gate) node is what you want?

You can open and close the gate at specific times, maybe using your "timerswitch" node.

The below flow will give one output every minute between 08:00 and 17:00 and one output only once at 17:00.  
you need to install `node-red-contrib-cron-plus` for this.

Have been using cron plus for quite some time now, never occured to me i can have independent outputs from cron plus for every schedule. 🤦‍♂️ I have created multiple cron-plus nodes across my flows. Is there any significant cpu power lost in multiple nodes working instead of one node with multiple schedules ?  
thanks for this.

no, either way, the difference is insignificant (but technically, fan out is less overhead due to zero comparisons (switch node) and less routes (less clones))

Yes, of course.

Inject nodes can open and close the gate at specific times.

Your START button together with a trigger can open the gate and close it after a defined period.

Your START button together with a trigger can open the gate and close it if no further messages have been received for a defined period.

And many other possibilities.
