random number for multi VM's all starting at same time

P: 1
linked to 'Can't get true random numbers'

but out app is running on multipul VMs and they all start at the same time, so we cannot use time as seed.

any ideas on how we can get a truly random number?

Have you tried? The "same" time may not be precisely the same when dealing with microseconds.

Yeah, it's doubtful all 4 are running in exact synchronization down to the millisecond. Even if they are, in addition to the time, you just need to introduce a new factor into the seed that is unique to each machine, like an IP address or something.
