Recently, I discovered that trying to convert a timestamp to a date within an Angular expression isn't functioning properly.
So, I attempted to do something like this:
<th>{{new Date(elem.timestamp}}</th>
Unfortunately, this resulted in an internal Angular error.
I'm curious why it's not feasible to cast to a Date within an Angular expression?
Since angular expressions are limited in their ability to execute arbitrary JavaScript code, such as creating new objects, you will need to utilize angular filters for this purpose.
Instead of
{{new Date(elem.timestamp)}}
You should use
{{elem.timestamp | date: 'yyyy-MM-dd'}}
For more information on the date filter, check here. Further details on filters can be found here.
When working with a Firebase Timestamp object (https://firebase.google.com/docs/reference/android/com/google/firebase/Timestamp), the following code can be used:
{{elem.timestamp.seconds*1000 | date}}
Expanding on @package's point, we can convert milliseconds to hours and seconds using any desired pattern.
< th >{{elem.timestamp | date: 'yyyy/MM/dd h:mm:ss a'}}< /th >When working with Firebase timestamp, my preferred method is:
{{ element.seconds * 1000| date:'short' }}
To achieve what you're looking for, it's recommended to utilize a library such as moment. Additionally, the functionality you require can be implemented using "filters".
For further assistance, take a look at angular-moment
If the timestamp is in milliseconds: Only showing Date:
{{elem.timestamp | date: 'yyyy-MM-dd'}}
Date and Time:
{{elem.timestamp | date: 'yyyy/MM/dd hh:mm:ss a'}}
Date and Time (24-hour format):
{{elem.timestamp | date: 'yyyy/MM/dd HH:mm:ss'}}
If your timestamp is in seconds, then simply multiply by 1000:
{{elem.timestamp*1000 | date: 'yyyy/MM/dd HH:mm:ss'}}
Successfully converting a timestamp into a date format within an Angular expression.
This can be achieved by using the following code snippet:
{{elem.timestamp | date: 'yyyy-MM-dd'}}
