[icu-support] Question about updating time zone data?

[Swamy, V. <VS...@wm...>]

Hi,

I am using ICU 2.6.1 for C++ and for reasons beyond my control, cannot
upgrade to the latest version. However, I do want to update the time zone
data in ICU. I have found what I believe to be the script
icu/source/tools/gentz/tz.pl which should be able to convert a tzdata2005r
tarball downloaded from ftp://elsie.nci.nih.gov/pub/. When I run the script,
I get a bunch of errors of the form:

Bad alias in tz.alias: Blah maps to non-existent zone blah. Please fix this
entry in the alias table.

My question is: Is all I have to do, remove the entries from tz.alias? And,
if the script runs through fine, should I be able to copy the resultant
timezone.txt file over the existing file in icu/data/misc/timezone.txt and
rebuild ICU normally?

Thanks,
Vikram
