I think you could use
http://golang.org/pkg/time/#Time.Zone to
occasionally check wether the time zone has changed since the script has
been started and then use
http://golang.org/pkg/time/#ParseInLocation to
output the time.

In this issue
https://code.google.com/p/go/issues/detail?id=6007
in answer #30 they mention that they use a monotonic clock on Linux
now with Go 1.3 and up which should solve this (this is the commit
https://code.google.com/p/go/source/detail?r=79f855ac890d ). What platform
and Go version are you using?
