#938 Schedule skews and random numbers

Andy Fisher — Wed, 05 Jul 2017 22:09:44 -0000

Hi Joe,

Unfortunately this issue has not been resolved but it is in the queue. Currently this issue can be circumvented through a use of a model generation script of some kind that randomly assigns a number to the schedule_skew.

I was able to find the cause of why using the random number assignment to schedule_skew doesn't work. global object properties that are part of the object structure do not support any of the variable assignments like transforms and random numbers. Some additions to load.c need to be made for object structure assignments.

Documentation and reference material for underground cable

Where can I find documentation on how the underground cable Z matrix calculation has been done in grid lab D. I have gone through the cpp code for underground cable (http://www.gridlabd.org/documents/doxygen/1.1/underground__line_8cpp-source.html), but need the reference material to know the underlying formulas and constants

#991 tzinfo.txt has incorrect offsets for Europe

David P. Chassin — Sun, 29 Jan 2017 20:46:01 -0000

It certainly looks like the Europe TZ database is shifted so that CET cities are listed as WET, EET as CET, etc.

tzinfo.txt has incorrect offsets for Europe

Derrick Oswald — Sun, 29 Jan 2017 18:40:54 -0000

In the Europe section of tzinfo.txt, entries are off by one hour. Entries for North Ameria appear to be corect.

For example:
MSK-4MSKS should be MSK-3MSKS - since MSK is UTC+3 (https://en.wikipedia.org/wiki/Moscow_Time)
EET-3EEST should be EET-2EEST - since Eastern European Time is UTC+2 (https://en.wikipedia.org/wiki/Eastern_European_Time)
CET-2CEST should be CET-1CEST - since Central European Time is UTC+1 (https://en.wikipedia.org/wiki/Central_European_Time)
WET-1WEST should be WET0WEST - since Western European Time is UTC (https://en.wikipedia.org/wiki/Western_European_Time)

Proof can also be had by using Google to search for "CET-1CEST" vs. "CET-2CEST" yielding 3380 hits vs. zero hits.

Many (if not all) the cities/countries listed do not belong to the time zones they are listed under.

For example:
EU/DE/Berlin is listed under WET (Western European Time), but is in fact in CET-1CEST (https://en.wikipedia.org/wiki/Berlin)
and many, many others.
