Improve Date Spoofing

[dillbyrne]

Currently only the time zone offset is spoofed.

Some date integer functions were originally included in the spoofing but they were dropped as they were causing page timeouts. Date locale strings will need to be set using the language headers for all the spoffed attributes to match. The selection of the time zone abbreviation is currently randomly selected when a timezone has been chosen. This could be improved to allow users to select the abbreviation in addition to the timezone.

During research I noticed the date strings are presented differently across different platforms such. This will have to be accounted for when spoofing.

Time based fuctions such as getHours() need to be spoofed in such a way as to not break functionality like the previous version. Moving the date/time spoofing logic into the inject script will probably address the breakage as the functions will return updated but spoofed data each time they are called.

I downloaded the source code from you and edited the timezone abbreviations as on windows tzutil timezones. It would be nice if you could add instead of the timezone hours in addon itself to country wise when changing timezone from firefox. I can send you the section I have edited and see if it has issues or not

Hi @bodaa . Do you mean the corresponding list items for the dropdown menu ? . Send me what you have and I'll get back to you when I get a chance.

One issue with that approach could be that multiple countries share timezones so for the entry which one do you pick. Another issue is that country timezones may not be that obvious to users where are numbers are, at least for languages that use 0-9.

In any case we could at the very least add a wiki entry for each time with corresponding countries.

Hi!
And what exactly does RAS change when changing timezone offset?
Thanks.
