S S,
Given this reoccurring issue I am taking a deep dive into dates and UTC as
I did previously with the days operator. I have gained a much deeper
understanding and will share the results shortly (80% completed)
The aforementioned inability to convert a variable to a date is clearly a
hindrance, for which I expect to find a work around,
However I can state that getting dates into the full serial date format,
and as a UTC value (as in the created and modified fields) is the best
approach because all tiddlywikis date support goes from there.
If you accept a day month or year and save them in three fields, you can
then use a macro to concatenate them and generate a serial date,
The next thing to establish is then how to save it as UTC rather than local
time so when you use it it will use the local time to display it.
I have used search and prefix in the past to list dates, so I need to work
out how to adjust local time to to UTC before searching.
I will share more tomorrow ie <+12 hours.
Regards
Tony
