  * * `format` - a format of date returned:
  * 	- `message` - returns a mime date as integer (unix timestamp)
- * 	- `message_str` - returns a mime date as string (UTC format)
  * 	- `connect` - returns a unix timestamp of a connection to rspamd
- * 	- `connect_str` - returns connection time in UTC format
  * * `gmt` - returns date in `GMT` timezone (normal for unix timestamps)
  *
  * By default this function returns connection time in numeric format.
