schroot -u root -c focal-amd64 -- sh -c "apt-get update; apt-get install -y tzdata python3-icu; echo 'zdump test\n----------'; zdump -v Asia/Gaza | grep 'Mar 26.*2022'; echo 'python3-icu test\n----------------'; python3 -c 'from datetime import datetime; from icu import ICUtzinfo, TimeZone; tz = ICUtzinfo(TimeZone.createTimeZone(\"Asia/Gaza\")); print(\"UTC offest is: %s\" % str(tz.utcoffset(datetime(2022, 3, 26))))'"
