I need next day as attribute. As I know, date manipulation by adding ms (e.g. ${now():toNumber():plus(86400000) ). With this solution I have a problem with the daylight saving: If date = "2016-10-29 12:00:00" ${date:toDate("yyyy-MM-dd HH:mm:ss"):toNumber():plus(86400000):format("yyyy-MM-dd HH:mm:ss")} This code results: "2016-10-30 11:00:00" I have built a pyhton solution, but I'm not realy happy with it: import java.io
from org.apache.commons.io import IOUtils
from java.nio.charset import StandardCharsets
from org.apache.nifi.processor.io import StreamCallback
from datetime import datetime
from datetime import timedelta
flowFile = session.get()
if (flowFile != None):
inDate = flowFile.getAttribute('inputDate')
outputDateName = flowFile.getAttribute('output date attribute name')
unit = flowFile.getAttribute('python timedelta unit')
quantity = int(flowFile.getAttribute('quantity'))
pythonDateFormat = flowFile.getAttribute('python date format')
kwargs = {unit: quantity }
outputDt = (datetime.strptime(inDate, pythonDateFormat) + timedelta(**kwargs)).strftime(pythonDateFormat)
flowFile = session.putAttribute(flowFile, outputDateName, outputDt)
session.transfer(flowFile, REL_SUCCESS)
Exist another solution with the given Nifi Processors? I'm using HDF 1.2.0.0.
