Australia/Darwin 1945..2007

[Sean B. Durkin]

To anyone who can help:

The data source file 'australasia' specifies that the Australia/Darwin
zone uses the rule Aus from 1-May-1899 onwards. But the Aus rule is
undefined for from 1945 onwards! I have copied the salient fragment of
the australasia file to the bottom of this message.

Am I missing something here? or is the data inconsistent?

Moreover, as a general rule, how should one interpret the application
of a tz "rule" for periods when the rule is not explicitly defined?

Thanks in advance, if anyone can advise.
Faithfully,
Sean B. Durkin
