It should also be noted that for historic records, the UK/Ireland area
is only valid for timezone data post 1970. The pre-1970 time frame will
only be correct if the 'backzone' data is included to correct
differences in the various islands in the area. Using those timezones
may only return the London data without any warning. Other areas of the
world have similar problems but there is the potential that the pre-1970
data has not be validated. There is not currently any service that can
be used to provide accurate pre-1970 due to there currently being gaps
in the historic data.
