I have a flow I want to execute daily at 1pm. It seems like the timestamp interval uses cron from what I gather so uses the unix timestamp to determine the time then set this as the time of the interval.
Is there a way I can use a timezone specific time so I don't need to calculate the time I actually need and factor things for daylight savings etc?
Are you using an Inject node? If so the time you specify is the local time. If it doesn't use the local time then probably the timezone on the machine running node-red is not correct.
