Nishant: Yes, that is a limitation of the idea; it doesn’t update more than every time the VM thinks is a minute. (Even if it updated every “real” minute, it would still be off by some seconds at the end of the minute, and this can confuse makefiles and such on shared filesystems.) For what I need, this limitation is more a matter of “isn’t as good as it could be” than “doesn’t work”, though.

hakre: Thanks for the comment; I’m glad to hear that it’s useful for you!

I like the approach. Each time my windows host system is back from hybernation, the debian vmware boxes were out of sync with their software time.

I once used a timeserver / ntp to sync the clock again but after reading your post I much more like this version.

Hey,

It doesn’t work if your clock is losing more than a minute in two minutes. Because the crontab fires by the system’s clock. So I saw the time update from 3:40 to 3:42 when the crontab fired.
