Events log file is capturing different time than Sys.time

shiny

Hi all,

In the below application, I am trying to capture the logging events. One strange thing I observed is, the Sys.time and the time it is showing when I perform input$bins is different. For example please refer below picture. The first line is the actual time(00 : 09 : 50) but the below lines is having a time that is different (18 : 39 : 50 and so on). May I know why is this happening? Can we have a actual time here?

ui.R

library(shinyEventLogger)

library(shiny)

set_logging(r_console = TRUE,js_console = FALSE,file = TRUE)



# Define UI for application that draws a histogram
shinyUI(fluidPage(

  # Application title
  titlePanel("Old Faithful Geyser Data"),
  
  # Sidebar with a slider input for number of bins 
  sidebarLayout(
    sidebarPanel(
       sliderInput("bins",
                   "Number of bins:",
                   min = 1,
                   max = 50,
                   value = 30)
    ),
    
    # Show a plot of the generated distribution
    mainPanel(
       plotOutput("distPlot")
    )
  )
))

server.R

library(shiny)
source("ui.R")
library(shinyEventLogger)


# Define server logic required to draw a histogram
shinyServer(function(input, output) {
  
  set_logging_session()
  log_output(Sys.time())
   
  output$distPlot <- renderPlot({
    
    # generate bins based on input$bins from ui.R
    x    <- faithful[, 2] 
    bins <- seq(min(x), max(x), length.out = input$bins + 1)
    
    # draw the histogram with the specified number of bins
    hist(x, breaks = bins, col = 'darkgray', border = 'white')
    
  })
  observe({
    log_output(input$bins,type = "New",status = "NEWSTATUS")
  })
})

Sys.time() is using the "IST" time zone (UTC +5:30) because of your system locale, the other lines are in "UTC" ( Coordinated Universal Time), using UTC is the standard method for storing timestamps.

Thanks. Wanted to check if it is possible to include IST time in events log??

Here is a resource with even more resources regarding shiny logs shiny logs
also, here is a great video regarding logs and debugging for Shiny that I think will help you overall
