st: Re: Seed and time

["Sergiy Radyakin" <Radyakin@aoek.uni-hannover.de>]

Hi, Sam!


Setting seed is enough:

. set seed 1

. di uniform()
.66818523

. di uniform()
.92796107

. di uniform()
.48448141

. set seed 1

. di uniform()
.66818523

However, if you initially set seed to be equal to current time (rather then 
the constant 1 here) than time matters.

Regards, Sergiy
