Hi,

is it possible to edit the created or last modify timestamp of a file i have upload to a azure blob container?

for example:
LAST MODIFIED 7/22/2017, 5:31:04 PM
CREATION TIME 7/22/2017, 5:31:04 PM

to:
LAST MODIFIED 7/22/2016, 5:31:04 PM
CREATION TIME 7/22/2015, 5:31:04 PM

No, this is not possible. This would break the audit trail and trust for file data in storage.

And why is there a function called BlobProperties.setCreatedTime(final Date createdTime) Method?

hello Sam, A followup question to the above link: setLastModified(final Date lastModified)

The documentation suggests that one can set the lastModified date. Is that not contradictory to the answer provided.

The setLastModified setter method is not public (it's protected) and is used to set the field value at runtime - it doesn't actually update the Last-Modified property of the Blob in Storage.
