There is a HISTTIMEFORMAT environmental variable, which allows you to set a time string display in the format specified when the history command is called.
As for not allowing individuals to set their own ~/.bashrc files, read the invocation section of the man page:

Finally, some advice. I can guess that English is not your native language, but simply posting a simple one-line question without any details explaining what you want to do or why can be hard to understand and is considered a little rude. You didn't even use a proper question form above, in fact.
Try using phrases like "How do I....?" and "What's the best way to ...?" Then add some details about what you are trying to do.
