- `utcnow()` returns a datetime object of the current time in the UTC timezone.
- For specific values: `utcnow().second`, `utcnow().minute`, `utcnow().hour`, `utcnow().day`, `utcnow().month`, `utcnow().year`, `utcnow().weekday()` and `utcnow().isoweekday()`.
- Using `utcnow()` will cause templates to be refreshed at the start of every new minute.
- `as_datetime()` converts a string containing a timestamp to a datetime object.
- `as_timestamp()` converts datetime object or string to UNIX timestamp. This function also be used as a filter.
- `as_local()` converts datetime object to local time. This function also be used as a filter.
