I'm exporting a find filter to Java that includes two dates.  The Java export offers this up:
Bson filter = new Document("expiration_dt", new Document("$gte", new java.util.Date(1644105600000L)) .append("$lt", new java.util.Date(1644192000000L)));
 
Can we change the Java export to use date strings or something more akin to the original ISODate format from the shell which was:

{ expiration_dt: \{ $gte: ISODate("2022-02-06"), $lt: ISODate("2022-02-07") }

}
 
Both PHP and Java use the long integer value for the date object, whereas all the other language exports use date from string or date from parts.
