Make has been driving me mad for the last week. It keeps on complaining about “modification time in the future”. Normally, this happens because you’re using rmeote files from a server which doesn’t have sync’d time. But this is rare these days. Anyway, it was complain that the file was 10E+06 seconds in the future; that’s a really, really big clock skew.

Did a bit of poking around. One possibility I found was that it was due to a limitation in FAT32; hmmm, not likely. Didn’t have time for more. I am at a conference; supposed to be paying some attention.

Anyway, the solution came to me today. Or rather the cause, because the solution was obvious. Turns up, when I changed timezone to Czech, I pushed the month back to August. What I don’t understand is that I was sure windows synced to a NTP server running somewhere. What does it do when you change the month?
