Hi Tony,
Thanks for the quick response, however what needs to go into the file
$wtzdata["US-Eastern"] = "America/New_York";
based on my data:
TZID
UTC+00:00) Dublin\, Edinburgh\, Lisbon\, London
TZID="(UTC+00:00) Dublin, Edinburgh, Lisbon, London":20171205T000000
TZID="(UTC+00:00) Dublin, Edinburgh, Lisbon, London":20171205T235959
