Timezone and Sessions Indicators with auto-adjust EST/EDT?

Anyone has a link to the auto-adjusted timezone and sessions indicators?

I'm using both but without daylight saving. I want the ones with auto EDT and EST.

When the time changes on the server, won't the time change also on the chart? And, if the time changes on the chart, won't the location where the indicator paints the screen colors for U.S./Europe/Sydney-Asia, change with it?

Or, am I missing something.

I'm using MT4 which is using London timezone.

I'm not sure whether the server changes EDT to EST automatically or DST in europe automatically.

More info.

GBP is one hour behind EUR in Timezone indicator.

20:42 now on MT4 time, which is London and GMT, no DST offset at the moment.
