Feature request: allow timezone to be specified

[daattali]

By default, the timeline displays times in local time, but it's possible to use moment.js to specify it to show in a different timezone; see https://github.com/daattali/timevis/issues/66

@IkerrSC @jpara3 FYI

What is intended to be is that the table that is shown in the timevis table gets the same time as the timeline shows.

Not sure if being able to enable

    var options{
        moment: function(date){
                      return vis.moment(date).utc();

          }
      }

will be enought

[daattali]

To do that, you would use timezone=0. But I didn't like that as much, I prefer the user being able to choose what timezone the timeline is displayed in (in the majority of cases, the user doesn't need to retrieve any data back so they don't even realize or care that it comes back in UTF. Most of the times it's only used for rendering, so it's good to choose what timezone it should be displayed in)

But where I have to do it? In timevis function?

          timevis(data,options=list(timezone=0)?

And to add for example, UTC+1?

               timevis(data,options=list(timezone=1)?

Thanks!

As the documentation says, it's a parameter of timevis. timevis(data, ..., timezone=1). It couldn't be used as an option because it required such specialized code, it's too much to expect a user to add moment: function(date){return vis.moment(date).utc();} so instead it's just a simple parameter

I have tried with

  timevis(data,.....,timezone=1) 

And I have get: Unused argument timezone=1

I have tried also

  timevis(data,.....,timezone=1) 

And it did not work Also I have tried adding

  var options{
          moment: function(date){
                   return vis.moment(date).utc();

         }
      }

And also not working!

Did you install the latest version from github in the past 30 minutes?

I have tried with it, but not working

 Couldn't normalize path in `addResourcePath`, with arguments: `prefix` = 'jquery-1.11.3'; `directoryPath` = '

Here my app code:

library(timevis)
library(shiny)

data <- data.frame(id=1,
  start=c("2019-01-10","2019-01-11"),
  end =  c("2019-01-11","2019-01-12")
  )

ui <- fluidPage(
  br(),
  br(),
  timevisOutput("timeline"),
  tableOutput("table")
)

server <- function(input,output){
  output$timeline <- renderTimevis(

    timevis(data,options=list(editable=TRUE,stack=FALSE),timezone=1)
  )

  output$table <- renderTable(
    input$timeline_data

  )

}

shinyApp(ui,server)

I tried installing the package just now on 3 different computers and did not have an issue. Try restarting your R session and reinstalling the package.

If you still see a problem with timevis and you think there's a bug, please submit a new issue separate from this

[JesusPF1981]

OK,

Now its working but only if I set the timezone=0. With this there is no problem (but the data are shown with one hour of delay:

But if I want to use a timezone, for example +1, then the timeline and the table show discrepancies:

[daattali]

What you're seeing is correct. For example, in the second example that you show, you're asking timevis to render as if it's in UTC+1, so in that timezone it's 00:00. If it's 00:00 in UTC+1, then in UTC it's 23:00. As I said a few times, timevis can only return information to shiny in UTC (that's what the Z means in the timestamp), so the return value of 23:00:00Z is correct because in UTC it is 23:00 when the timevis shows 00:00

If you still believe there is a bug, please submit a new issue for better organization

[JesusPF1981]

OK

Thanks for all!
