Using the pretty time library to show a time in a human readable format in JSF

I happened to use pretty time 1.0.6 to display an interval between two points in time in a human readable format.

There is an in-built JSF converter,

com.ocpsoft.pretty.time.web.jsf.PrettyTimeConverter

but it supports only java.util.Date objects.

I happened to use the following converter for org.joda.time.DateTime

@ManagedBean
@ApplicationScoped
public final class PrettyJodaTimeConverter extends PrettyTimeConverter
{
    @Override
    public String getAsString(final FacesContext context, final UIComponent component, final Object value)
    {
        if (value instanceof DateTime) {
            return super.getAsString(context, component, ((DateTime) value).toDate());
        } else {
            return super.getAsString(context, component, value);
        }
    }
}

This displays an interval, for example, "4 hours ago" on <h:outputText>, for example

<h:outputText value="#{productInquiryManagedBean.lastInquiry}"
              converter="#{prettyJodaTimeConverter}"/>

But I need to display a message on <p:growl> (or <p:messages>, <h:messages>) based on a conditional check in a JSF managed bean. Therefore, this converter cannot be used (please suggest, if it can be used). Instead, I need to manually format it in the managed bean in question like so,

private DateTime lastInquiry;
private String emailId;
private Product product;

if(productInquiryService.isPeriodExpired(30, emailId, product))
{
    lastInquiry=productInquiryService.getDateTimeOfLastInquiry(email, product);

    Locale locale = FacesContext.getCurrentInstance().getViewRoot().getLocale();
    PrettyTime time=new PrettyTime(lastInquiry.toDate(), locale);
    time.setLocale(locale);

    FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, Utility.getMessage("faces.message.error"), Utility.getMessage("inquiry.min.time.expire", time.format(new Date()))));
}

This displays a message on <p:growl> like - "You made an inquiry 4 hours from now".

Can this message format be changed to "You made an inquiry 4 hours ago" exactly as displayed on <h:outputText> as shown above?

Also, the interval format displayed here is not localized to a particular locate from a resource bundle. It always seems to be using its default locale. The message produced by PrettyTime#format() should be localized.

I was passing wrong parameters to the constructor. Hence the wrong message indicating a future time. They should be like as follows.

PrettyTime time=new PrettyTime(new Date(), locale);
time.format(lastInquiry.toDate());
//lastInquiry is fetched from the database which a customer made an inquiry on.

It now displays the correct (past time) format like "4 hours ago".

Regarding the locale I was looking for was HI (actually hi_IN, Hindi in India) is not available in the resource bundles (in the com.ocpsoft.pretty.time.i18n package) supplied in the library even though it is mentioned there in the i18n and multiple-languages support section.

Grails and Angular: GSP plugin tag inside ng-repeat loop

I'm working in a Grails project that uses Angular.

I use a plugin called PrettyPrint in order to have "twitter like" time (i.e. formatting dates like 'moments ago').

I want to use the plugin inside a ng-repeat loop.

<tr ng-repeat="notification in notifications">
...
    <td><prettytime:display date="${notification.date}" /></td>
...
</tr>

In the above code, the error thrown is Cannot get property 'date' on null object. (it doesn't recognize notification item from angular loop).

If I use {{notification.date}} it shows the date.

How can I deal with both, the plugin and Angular?

Converting timestamp from parse.com in java

I'm getting my object's createdAt timestamp back from parse.com as 2014-08-01T01:17:56.751Z. I have a class that converts it to relative time.

public static String timeAgo(String time){
  PrettyTime mPtime = new PrettyTime();

  long timeAgo = timeStringtoMilis(time);

  return mPtime.format( new Date( timeAgo ) );
}

public static long timeStringtoMilis(String time) {
  long milis = 0;

  try {
    SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    Date date   = sd.parse(time);
    milis       = date.getTime();
  } catch (Exception e) {
    e.printStackTrace();
  }

  return milis;
}

The problem is that this parses the date wrongly. Right now the result says 4 decades ago and this very wrong. What I'm I doing wrong?

Parsing ill-formated date-time string in Java

In one sentence: Should I be able to parse "04 Dec 2014 pm 1:58" by PrettyTime?

Descriptive: I am in need to parse & get proper date format from some ill formatted date-time string. e.g. "04 Dec 2014 pm 1:58". When I do parse this example string, I get : "Thu Dec 04 02:59:33 ALMT 2014" which is I believe my current time stamp.

Consideration: if I had only this single ill-format, I could write my SimpleDateFormat. But there can a good varieties of formatting which are mostly going to be ill-formatted.

Can any of you kindly tell me, whether should I expect PrettyTime to parse for this type of ill-formatted string? Or could you please point to any Java library which can handle these type of ill formatted date strings in Java?

How to describe duration in Android?

I'm writing small app and I need to write duration of sport event in i18n. Im using PrettyTime library for date, but when I attempt to use DateUtils or PrettyTime, I have issues..

For example I want to say that duration is 2 minutes. I need some way to pass it to library which supports i18n and accept milliseconds and return Chars.

In android we have:

com.android.internal.R.plurals.duration_minutes

But I can't access to it from my App. Is there any way to make it using correct way and not writing own plurals for all languages?

Thank you
