Does the time picker support timezones?

[uberllama]

Thanks very much for putting this repo together. I'm using moment.js to format my datetimes, which are returned from the server in iso8601 format. Wondering if your time picker is TZ aware, or if I'll have to mutate the value to append the current user's TZ via moment. Cheers.

Hey there,

Good question, the datepicker doesn't make any assumptions about timezones, all it expects is a valid Date object as input in the value prop. Mutating the value, once set, will probably not work as all date operations done internally by the widget return a new date instance.

The one place it may not give you what you want is when typing a date into the input and you need to parse that string into a date. I am not sure if the picker will maintain the UTC Offset (my assumption is it will but i am not sure). Luckily if it does not you can easily hook into the picker to make it behave however you want with Moment.js, either through the parse and onChange props. You may want to wrap the widget to encapsulate the behavior more generally like:

var TZDateTimePicker = React.createClass({
  render(){
    return <DateTimePicker {...props}  parse={this._parse} onChange={this._change}/>
  },

  _parse(str){
    var formats = this.props.parse // the user inputed format strings
    return MyTzAwareParseFormat(str, formats) // such as using Moment.js 
  },

  _change(date, dateStr){
    date = EnsureCorrectTz(date) // Moment.js here as well probably?
    this.props.onChange(date)
  }
})

I found in the Git repo that using MomentDateTimePicker is suitable for your request.
