timezone argument fails in shiny but works in console

[sanjmeh]

Hi Dean,

First of all thanks for this excellent package. I started using it today and ran into a possible bug.

This line works in shiny.

output$tline <- renderTimevis({
    timevis(data.table(id = 1:6,content = c("Uplift 202L","Uplift 103L","Downlift 4500L","Uplift 450L","Downlift 2000L","Uplift 520L"),start = Sys.time() - hours(as.integer(rnorm(6,100,sd = 50)))))
  })

But if I run the same line with the arrgument timezone added, it fails. Following is a little more context form the shiny app.
Loaded packages:

pacman::p_load(futile.logger,shiny,shinyalert,shinybrowser,plotly,shinydashboard,tidyverse,lubridate,data.table,
               fontawesome, shinyWidgets, gt, shinycssloaders,timevis)

extract of ui:

tabItem(tabName = "timeline",
              box(width = 12, title = "Time Line",status = "success",solidHeader = T,
                  selectizeInput("tanktline","Island Name",choices = vehdt$veh,width = "20%"),
                  timevisOutput("tline") |> withSpinner()
              )
      )....

extract of server function:

output$tline <- renderTimevis({
    timevis(data.table(id = 1:6,content = c("Uplift 202L","Uplift 103L","Downlift 4500L","Uplift 450L","Downlift 2000L","Uplift 520L"),start = Sys.time() - hours(as.integer(rnorm(6,100,sd = 50)))),timezone = 5)
  })

The output timeline is a static and distorted image.

However, this works in the console:

 timevis(data.table(id = 1:6,content = c("Uplift 202L","Uplift 103L","Downlift 4500L","Uplift 450L","Downlift 2000L","Uplift 520L"),start = Sys.time() - hours(as.integer(rnorm(6,100,sd = 50)))),timezone = 5)

As a summary,
when I remove the timezone argument, the shiny app works else it results in a bad output.

I'm not able to reproduce an issue.

The code you provided is not reproducible so I modfiied it a little bit but I've been unable to see a problem. Here is a shiny app using the same timevis data you provided and using a timezone, and it works.

library(shiny)
library(timevis)
library(lubridate)

ui <- fluidPage(
  timevisOutput("test")
)

server <- function(input, output, session) {
  output$test <- timevis::renderTimevis({
    timevis(
      data.frame(
        id = 1:6,
        content = c("Uplift 202L","Uplift 103L","Downlift 4500L","Uplift 450L","Downlift 2000L","Uplift 520L"),
        start = Sys.time() - hours(as.integer(rnorm(6,100,sd = 50)))
      ),
      timezone = 5
    )
  })
}

shinyApp(ui, server)

I'm closing this issue for now. If you still believe there's a problem, please post a minimal fully reproducible example.
