The included timestamp is the number of seconds since epoch, so a BsonObjectId time part has only
a precision up to the second. To get a reasonably unique ID, you _must_ set onlyTimestamp to false.
Crafting a BsonObjectId from a timestamp with fillOnlyTimestamp set to true is helpful for range queries,
eg if you want of find documents an _id field which timestamp part is greater than or lesser than
the one of another id.
If you do not intend to use the produced BsonObjectId for range queries, then you'd rather use
the generate method instead.
if true, the returned BsonObjectId will only have the timestamp bytes set; the other will be set to zero.

The returned BsonObjectId contains a timestamp set to the current time (in seconds),
with the machine identifier, thread identifier and increment properly set.
