Hey guys, I am trying to calculate the daily time difference to determine the rate of light dimming between sunset and dusk. I have tried a couple of option but all of them seems to have a limitation. Here are the options I tried and why they failed. -To calculate the time difference I tried to save the store the time in a variable in better logic app. The problem here is that the time stored in the variable are only the two digits of de 24 hour format. - I Tried using mathjs in betterlogic by subtracting “dusk-sunset” but I get weird value as output. So to sum up I calculate time difference because I cant store the data in flow nor script. And I cant mathematically calculate the difference . Any tips? ---

you could make a Homescript and send two parameters, time1 & time2 convert them to timestamps, substract them, and than you could convert that back to time. or… use my script i posted recently, in Dutch: > [@HomeyScript seconden naar uren, minuten en seconden](https://community.homey.app/t/homeyscript-seconden-naar-uren-minuten-en-seconden/47643): > > Echt super nuttig is dit niet, maar wel leuk voor de mensen die graag dingen bijhouden. Ik heb dit HomeyScript gemaakt om de uitkomst van een stopwatch leesbaarder te maken. Ik heb deze apps daarvoor in gebruik: Met chronograph kun je een stopwatch starten en stoppen. De tijd daartussen wordt opgeslagen in de tag: looptijd (s) Dit is dan opgeslagen in seconden, bijvoorbeeld 42123 seconden. Maar dan weet je nog niet bijster veel. Dus… als je dan het volgende invult bij Als dan zie je de uitk… ```auto var dateParts = '17-09-2013 10:08'.match(/(\d+)-(\d+)-(\d+) (\d+):(\d+)/); console.log(dateParts); // ["17-09-2013 10:08", "17", "09", "2013", "10", "08"] ``` source: [jquery - Converting a datetime string to timestamp in Javascript - Stack Overflow](https://stackoverflow.com/questions/18849351/converting-a-datetime-string-to-timestamp-in-javascript#18849896) ---

Question for Advanced Flows: Is there an option to temporarily suspend a flow? ---

It’s a bit Off Topic But, yes, that can be done the same way as in the OLD flows: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/a/7ad3bbc87accd54c4f14cde203cc605bdafa6345.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/4/3422fa5dbbf41c88064da81d0718f611fb531671.png) ---
