WampServer

After successfully installing WAMP5 on my local WinXP box and setting up mailserver functionality using Goggle Apps (see other post on how this was done), I receive the below error msg. when using the email confirmation special page for MediaWiki.

Although it implies email was not sent, it actually was and I was able to respond back with the confirmation email. Does the below error msg. indicate a modification I need to make in my WAMP5 configuration or is this something specific to MediaWiki and I need to seek a solution from their forum?

------------------------------------
Could not send confirmation mail. Check address for invalid characters.

Mailer returned: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Denver' for '-6.0/DST' instead.
------------------------------------
Thx. in advance,
