Dear Colleagues, Can you recommend a simple and cheap way to "time stamp" files?
I found that commercial labnotebook programs are either quite expensive or not easy to adapt to: I don't want to change my workflow and inflate it with tedious procedures to upload each file I am working with (and changing it every now and then) to an internal server and then even find out that the current project cannot hold more files and/or data. In my daily lab life, I obtain data in files from different machines (like photometers, protein chromatography system, online publications / web material printed into pdfs, fotos and so on. Although I am still keeping a written journal for important experiments, a lot of my work is electronically recorded and described. Usually, all files related to a project are kept in a structure of subdirectories, so it's easy to pack them a project into an archive (eg (g)zip) for backup purposes and of course to finalize it. I wonder if there is a way to "envelope" such an archive with a timestamp that is commonly (ideally lawyer- and court-proof) recognized as valid. So it should not depend on my local computer networks' internal clocks, but rely on a public non-fakeable timeserver. Usually, I have a Linux (OpenSuse11.x) environment for my work, but the ideal solution also should work with windows. Any suggestions?
