I have noticed that when I specify ":" in date or time placeholder the output is "/"
What am I doing wrong?? 
Cheers,
Bill
Sorry My mistake... Though why not?
WOW....
Possibly because : is an HFS path delimiter ?
Yup… I would never have thought… oh well… I always wondered why I have seen many time separators with points in the file name… go figure… 
LOL…
Unless you actually need to "read" the date/time in the file name, why not just eliminate everything but the numbers? As in

What about the © symbol? Could that be a problem?
The C commercial © is not the problem. Though the colon is? Funny I didn't know this or I did and old age is finally having the best of me....

Once again going to bed smarter tonight.. LOL... 
Your reference says to "avoid":
Non-alphabetical and non-numerical symbols
I would definitely put the © symbol in that category.
LOL It works for me today... Though you are right this most probably will bite me in the ass in the future... Will fix this..
Thank you @JMichaelTX for the insight..

Hey Bill,
I wouldn’t worry about the copyright symbol too much. 
When I want an easily read date and time in a file name on the Mac I usually write it like this:

That centered dot is produced with Shift-Opt-9. [ Edited 2015.08.19 ]

Nice and clean Just the way I like it… AND KISS…
I usually do this when I name files it’s clean and readable.
I wish we had a comment option when saving files though. I use comment on files for easly find with spotlight.
The Set File Attribute action can set the comment of a file.

After the previous post I did a search on Keyboard Maestro Wiki, Love this App . I have been going through Keyboard Maestro Wiki. it's great...
I can't get this to work?
Do you mean (option-8) Bullet, Hex 2022 ??
Sorry You Meant Option+Command+Shift+9 ?
Shift-alt-9 on my Mac produces the centered dot known as an “interpunct”
That's it...
Thank you @rolian
