modo.dateFormatter

The dateFormatter object is no creatable element, but attaches itself to the modo core. It adds methods to the modo core to display times and dates in different formats. It can automatically correct time offsets across different timezones as well.

The dateFormatter is fully internationalizable - just overwrite the object properties that contain the strings dates are constructed from to make dates appear in your locale flavor.

Pro tip: Simply create an object (maybe in a JSON file) that contains your localized properties and overwrite the original dateFormatter language properties by using underscores extend method:

_.extend(modo.dateFormatter, myLocalizedObj);

Heads up: This is not a element constructor!

MONTH_NAMESArray

Array of fully written month names. Defaults to:

['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']

SUFFIXArray

A suffix string to be appended in some cases. Defaults to:

['st', 'nd', 'rd', 'th']

TODAYString

String that represents the word "today". Defaults to today.

YESTERDAYString

String that represents the word "yesterday". Defaults to yesterday.

LASTString

Micro-Template string for outputs of the dateToFancyString() method like "last week" or "last month". Defaults to last %v. %v is being replaced in that string.

FUZZY_SECONDSString

String that represents a very short timespan. May be returned by dateToFancyString(). Defaults to about a minute ago.

NEVERString

String that represents a time that has never been there. Usually expression for the unix time 0.

REL_UNITSArray

Array of time units to be used by different methods. Defaults to:

['seconds', 'minutes', 'hours', 'days', 'weeks', 'months', 'years']

REL_PASTString

Micro-Template string for outputs of the dateToFancyString() method like "20 seconds ago". Defaults to %v %u ago. %v is being replaced by the value, %u is being replaced by the unit.

REL_FUTUREString

Micro-Template string for outputs of the dateToFancyString() method like "in 10 minutes". Defaults to in %v %u. %v is being replaced by the value, %u is being replaced by the unit.

REL_CURRENTString

String that represents the current moment in time. Defaults to right now.

DEFAULT_FORMATString

String that represents the default output format for a full date, if dateToFancyString() notices a difference to now that is greater than one week. Defaults to: F jS, Y (renders to: "April 5th, 2015").

LOCAL_TIMEZONEInteger

Automatically set timezone offset. This is the UTC offset in hours, the USER uses on his side.

REMOTE_TIMEZONEInteger

Automatically set timezone offset. This is the UTC offset in hours, the SERVER uses on his side. Defaults to the same timezone as the user, so no corrections are made. Set this to the servers real timezone to make the library automatically correct all time output while normalizeTimezones is set to true.

normalizeTimezonesBoolean

Should the library automatically correct time outputs from remote timezone to local timezone? Defaults to true.

Methods

convertTimezone(inDate, toOffset, fromOffset)Date

Takes a date or timestamp and converts it to another timezone.

dateToFancyString(inDate, dateFormat, options)String

Takes a date object or timestamp and will return a "fancy" string representation which is most pleasant for users to read. Dates that are more than 7 days away from the current time will be rendered as a "full" date using the DEFAULT_FORMAT property.

Example output:

• 10 minutes ago
• Today, 11:15
• Yesterday, 22:00
• Last tuesday

The following properties can be passed into the method in the options object to overwrite the classes default settings:

{
    normalizeTimezone: true,
    localTimezone: -2,
    remoteTimezone: 2
}

dateToRelativeString(datePast, dateNow, options)String

This creates a "relative" string, as used often in applications and social networks. Instead of printing out the precise datetime, it comparing the two dates and produces outputs like "x minutes ago".

Also works into the future.

Example output:

• 10 minutes ago
• In 2 weeks
• 3 years ago

The following properties can be passed into the method in the options object to overwrite the classes default settings:

{
    normalizeTimezone: true,
    localTimezone: -2,
    remoteTimezone: 2
}

dateToString(format, inDate, options)String

This outputs a string with a formatted date and follows the PHP date() specification.

The following properties can be passed into the method in the options object to overwrite the classes default settings:

{
    normalizeTimezone: true,
    localTimezone: -2,
    remoteTimezone: 2
}
