Get date modified incoming file using SFTP adapter

Hello,

Currently we have an integration which reads a CSV file from a server. We would like to read the last modified date of that file as well, in the camel file language it shows that the correct expression is ${date:modified}. However, this is not working in our integration; the property is not filled and does not show up in trace logging.

Can someone tell me whether its possible to read the last modified date of an input file and if yes, which expression is required?

Thanks in advance!

Bram
