[REBOL] [ANN] time-in-digits.r 1.3.0

Hooray!
I have updated my 'time-in-digits function so that it can be used with
the /precise refinement for 'now.
I use 'time-in-digits exhaustively, because it can be used to create
sequential session IDs over time and to create sequential file names
over time.
Because it can now handle the /precise refinement, it is very unlikely
you will create the same session ID for multiple connections to a CGI
interface (which was a possibility previously since more than one
person might submit to CGI within the same exact second. Now
there would only be a problem if more than one person might submit
to CGI within the same exact thousandth of a second.)

Purpose: {
Convert the date and time into a string of digits.
}
Comment: {
Use this function to create a string of digits denoting
the date and time. This is useful, especially for creating
sequential session IDs. If used with 'now to create a file
name, the newest file will always appear at the end of
a directory.
