## Overview

shinyTime provides a `timeInput` widget for Shiny. This widget allows intuitive time input in the

`hh:mm:ss` or `hh:mm` (24-hour) format by using a separate numeric input for each time

component. Setting and getting of the time in R is done with date-time objects.

## Installation

```{r eval = FALSE}

# Install from CRAN

install.packages("shinyTime")

```

## Usage

As the `shinyTime` package mimics the existing shiny functionality, using the package is easy:

```{r eval = FALSE}

ui <- fluidPage(

  # Using the default time 00:00:00

  timeInput("time1", "Time:"),

  # Set to current time

  timeInput("time2", "Time:", value = Sys.time()),

  # Set to custom time 

  timeInput("time3", "Time:", value = strptime("12:34:56", "%T")),

 

  # Set to custom time using hms

  timeInput("time4", "Time:", value = hms::as_hms("23:45:07")),

  # Set to custom time using character string

  timeInput("time5", "Time:", value = "21:32:43"),

  # Use hh:mm format

  timeInput("time6", "Time:", seconds = FALSE),

  # Use multiples of 5 minutes

  timeInput("time7", "Time:", minute.steps = 5)

)

```

Note that setting an initial value can be done with

[`date-time`](https://www.rdocumentation.org/packages/base/topics/DateTimeClasses) (in the same way as setting

a date in `dateInput` can be done with a `Date` object), but also with an [`hms::hms`](https://hms.tidyverse.org/reference/hms.html) object or character string in `hh:mm:ss` format.

The value retrieved will be a `date-time` object (`POSIXlt`). You need to convert it to character to be able

to show the time, as the default character representation does not include time. For example:

```{r eval=FALSE}

server <- function(input, output) {

  # Print the time in hh:mm:ss everytime it changes

  observe(print(strftime(input$time1, "%T")))

  

  # Print the time in hh:mm everytime it changes

  observe(print(strftime(input$time4, "%R")))

}

```

For a demo, visit the [online example app](https://burgerga.shinyapps.io/shinyTimeExample/) or try the 

`shinyTime::shinyTimeExample()` function.
