Hi @Erik,  
The flows you published are very nice. I have about the same question, but…

I have a jsonfile where I get an hourly weather forecast. How can I get the data for example for 4 O’Clock instead off 3 O’Clock?

{“plaatsnaam”:[{“plaats”:“Utrecht”}],“data”:[{“tijd”:“1564405200”,“tijd\_nl”:“29-07-2019 15:00”,“offset”:“07”,“loc”:“none”,“temp”:“26”,“winds”:“2”,“windb”:“2”,“windknp”:“4”,“windkmh”:“7.2”,“windr”:“190”,“windrltr”:“Z”,“neersl”:“0”,“luchtd”:“1011”,“luchtdmmhg”:“758”,“luchtdinhg”:“29.84”,“hw”:“0”,“mw”:“0”,“lw”:“29”,“tw”:“29”,“rv”:“41”,“gr”:“155”,“cape”:“281.10”,“cond”:“3”,“ico”:“3”,“samenv”:“Halfbewolkt”,“icoon”:“halfbewolkt”},{“tijd”:“1564408800”,“tijd\_nl”:“29-07-2019 16:00”,“offset”:“08”,“loc”:“none”,“temp”:“27”,“winds”:“2”,“windb”:“2”,“windknp”:“4”,“windkmh”:“7.2”,“windr”:“191”,“windrltr”:“Z”,“neersl”:“0”,“luchtd”:“1011”,“luchtdmmhg”:“758.2”,“luchtdinhg”:“29.85”,“hw”:“0”,“mw”:“0”,“lw”:“35”,“tw”:“35”,“rv”:“39”,“gr”:“176”,“cape”:“281.29”,“cond”:“3”,“ico”:“3”,“samenv”:“Halfbewolkt”,“icoon”:“halfbewolkt”},
