If you want to change that, file a bug report upstream.

Why do you think that hard-coding (even if modified at install-time)
the time-zone is better than letting php figure it out at runtime?
"EST/-5.0/no DST" comes from a call to the localtime_r(3) function,
refer to its manpage for more information.
