Sure, I don’t know if I did it the most efficient, but it works.
You need the folowing nodes installed:
node-red-contrib-simpletime (this generates a date/time)
node-red-contrib-moment (this changes the timezone)
First I use a “inject” node that executes every second. This activates a simple time node that generates time / date then I connected that to a “Moment” node that adjusted the timezone, finally it’s coupled to a text UI output.
For the date I did the same, but instead of every second, I execute the inject node every minute. A better way was to execute the simple time node every time 0:00 is passed, but I was lazy 
I added also a translation function to translate the weeks and months to dutch, but if you want to keep it English, you can remove it.
I did not want to couple it to the “every second” node. The extra time / date queries and translating the weeks / months adds useless workload to the system.
I also personaly store the time and date in a global variable (not shown here). If nobody’s home (detected by the “smart presence” Homey app) it uses this variable to generates a list with time/dates if the front doorbell is ringed.
Here’s the JSON code:
