Hello, sorry to bring this back from the dead, but I'm having this problem as well and would like to know what the consequences are, as I'm in a different situation than the OP.
I'm building a website using font files from typography.com. I publish the project and they give me a zip with the font files. I move the files to the websites development folder, and all of a sudden resilio sync goes nuts with "XXX has invalid modification time and may cause other files to be rewritten" errors.
Are you saying that the archive and included files that I downloaded from the font company came with invalid timestamps, or maybe a timestamp from a different timezone, so it is causing a conflict?
I'm wondering what will happen to the files at this point. I need these new files to remain in place. These files are in a completely different directory than the old font files that they are replacing, so I don't understand where this error is coming from.
For example, the old files are \\dev\website\assets\fonts\version1
And the new files are \\dev\website\assets\fonts\version2
I delete version one, move version2, and then I get nailed with dozens of these errors. Why the errors if there are no other files to conflict with? Is it simply because the timestamp is so far out of sync of the real time?
Thanks for your expertise and advice on this.
