We have CRM 365 online (UCI) dynamics in North America 2 and I have noticed an error using the ADDDAYS (whole number, date and time) brought to our attention by out business only recently. We have a field called esu_mostrecentreferral, we add 45 days to this field and we get a new date in our 45 days field, however if you set this field (esu_mostrecentreferral) to 9/24/2021 the 45 days calculation is 1 day off, this happens until (arbitrary date of 11/8/2021 where the 45 days calculation works again, this is a date only field and there are no processes running in the background on this field, there are no scripts or anything else on this field, yet the calculation seems to be off. I've tried re-creating this field in another application and in new environments, and it is giving the same error, has anyone seen this and can also replicate it? and is there a way to resolve it besides putting in an incident with Microsoft?
Screen shots below of the date 9/23/2021 and 9/24/2021 returning the same date which should not happen.
