+#### **Display**
+| Name | Description | Type | Required | HarmonyOS Support |
+| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- | -------- | ----------------- |
+| format | This is the most robust display option. It takes a string of tokens and replaces them with their corresponding values. | function | no | yes |
+| fromNow | A common way of displaying time is handled by moment#fromNow. This is sometimes called timeago or relative time. | function | no | yes |
+| from | You may want to display a moment in relation to a time other than now. In that case, you can use moment#from. | function | no | yes |

+| calendar | Calendar time displays time relative to a given referenceDay (defaults to the start of today), but does so slightly differently than moment#fromNow. | function | no | yes |
+| diff | To get the difference in milliseconds, use moment#diff like you would use moment#from. | function | no | yes |
+| valueOf | moment#valueOf simply outputs the number of milliseconds since the Unix Epoch, just like Date#valueOf. | function | no | yes |

+| toJSON | When serializing an object to JSON, if there is a Moment object, it will be represented as an ISO8601 string, adjusted to UTC. | function | no | yes |
+| toISOString | Formats a string to the ISO8601 standard. | function | no | yes |
+| toObject | This returns an object containing year, month, day-of-month, hour, minute, seconds, milliseconds. | function | no | yes |
+| toString | Returns an english string in a similar format to JS Date's .toString(). | function | no | yes |
+| inspect | Returns a machine readable string, that can be evaluated to produce the same moment. Because of the name it's also used in node interactive shell to display objects. | function | no | yes |
+

+| isDST | moment#isDST checks if the current moment is in daylight saving time. | function | no | yes |
+| isLeapYear | moment#isLeapYear returns true if that year is a leap year, and false if it is not. | function | no | yes |
+| isMoment | To check if a variable is a moment object, use moment.isMoment(). | function | no | yes |
