[Zope] DateTime and TimeZone
I installed zope 2.7.6 on a windows 2000 machine. This machine is set
to the pacific timezone.
When I run python from the command line, and check DateTime, I get:
>>> from DateTime import DateTime
>>> DateTime()
DateTime('2005/09/06 23:55:29.620 GMT-7')
The 'GMT-7' is the Mountain timezone. The actual time should read
DateTime('2005/09/06 23:55:29.620 GMT-8') for the Pacific timezone.
What controls the default timezone behavior of DateTime on Windows? How
can I get this working correctly?
Thanks,
Mark

Re: [Zope] Truncating strings with DTML
easy: You don't need to use _.string.legacy() functions. Just put your python expression inside the quotation marks. If you're new to python, don't let DTML be your place to learn python.

[Zope] Truncating strings with DTML
Hi All, I'd like to take a string like: /Computers/Data_Formats/Almost_Every_File_Format_in_the_World and cut it down to: /Computers/Data_Formats using DTML. I've tried to count to the last "/", and then truncate the string with ljust, like so: However, ljust/rjust won't truncate the string. In the case above, I know that I want to truncate the string to 23 characters (/Computers/Data_Formats). Is there a way to accomplish this in DTML? If not, any suggestions?

It got *much* worse when CMF shifted to use subversion, which has many more bookkeeping files in the .svn directories. Plone developers who work on Windows sent up an anguished cry just after we switched over, while they were trying to prepare their 2.1 release candidate. > I believe Tres has now fixed this. I applied a tourniquet, which was the major reason for pushing out the 1.5.3 release. Mark Hammond volunteered (at the Plone Symposium in New Orleans) to look at the feasibility of a better solution which would use the native Win32 file monitoring APIs: http://www.zope.org/Collectors/CMF/367 As Chris noted, running with 'debug-mode off' also avoids this issue, if you can't upgrade CMF for some reason (and you *should* be running this way if performance matters, anyway).
