Hi,
i wrote a program in D in win32 (commandline), and it works fine.
then i decided i would try and compile it using the linux port of D from
www.opend.org
it works, but only if i comment out my usage of getUTCtime().
the error message is this:

[root lvs dli-0.1.2]# ./dli passGen.d
passGen.o: In function `__endif_599':
passGen.o(.text+0x30ff): undefined reference to `_D4date_10getUTCtime_FZl'
collect2: ld returned 1 exit status

what im using it for, is to further randomise the random seed when creating the
random number generator.
is there a way i can make getUTCtime() work in linux? or some other time
function i can use that will work? or even some other method of getting a unique
number for the rand_seed() func?
thanks,

Nick

There's the time function, which returns in seconds, and you can open 
and read from "/dev/random", which is nondeterministic because it 
samples from the computer state and external input.
