Hi

use Time::HiRes qw (gettimeofday);
my ($secs,$milliseconds)=gettimeofday(); my $trans="$secs$milliseconds";

Sometimes the length of $trans is 16 but sometimes it is 15. Shouldn't
it be 16 always?

The length of microseconds (not milliseconds) will be 5 digits one out of
ten times, because it's value is less than 100000 microseconds. In one
out of a hundred times it will be 4 digits, etc. If you rely on the
length of it, you should probably use sprintf.

Hi

Of course, I see that now. I need the length to create a unique number of
standard length. sprintf will do that.
Many thanks.

John
