You can follow this guide I wrote, you export Gerber, IPC and Pick and Place file manually and then pack it all up in a format we can process. It is a little more work than just upload the eagle board file, but it gives you more control about what you would like to export and with which format.
This way you can get the time stamp in your format and also exclude a solder paste layer.
This does not answer my question. I asked about E-Check of the produced boards. Reading
Please note that we ignore any IPC file that comes from unsupported EDA-applications. If you want Smart Tests, please upload your CAD file, or follow the described upload method for supported EDA-applications. Please have a look here to see for which EDA-applications we support Smart Tests.
lets me assume IPC file in a pure Gerber upload is ignored!
