[amibroker] Timeshift change due to summer time

["sursod" <sursod@xxxxxxxxx>]

When America changes to daylight saving time 2 weeks ahead of 
Europe, "timeshift" for intraday setting becomes one hour less. If the 
intraday setting is changed to give the correct timestamp of 9:30 for 
the opening bar of the current period, all previous opening bars have 
time stamp of 10:30. This will louse up any TA system based on day 
session only intraday bars.

As far as I can see there is only one day session hour setting and it 
is global (cannot vary this according to prescribed time periods) I 
have tried changing timeshift, day session hours, merge 2 lots of data 
collected using different settings. Nothing works.

Clues anyone? Thanks.
