Answer 1

First, we can use $addFields or $set to add new field (temporary) to document which will hold time difference. (in milliseconds)

db.collectionName.aggregate([
  {"$addFields": {"timeDiff": { $subtract: [new Date(), "$updatedDt"]}}}
]);

Now, we will use those fields to filtering records using $match

db.collectionName.aggregate([
 {"$addFields": {"timeDiff": { $subtract: [new Date(), "$updatedDt"]}}},
 {$match: {"timeDiff":{ $gte: 2* 60* 60* 1000},"status":"in-progress"}}
]);

Now, we can remove additionally added field using $project

db.collectionName.aggregate([
 {"$addFields": {"timeDiff": { $subtract: [new Date(), "$updatedDt"]}}}, 
 {$match:{"timeDiff":{$gte: 2* 60* 60* 1000},"status":"in-progress"}},
 {$project: {"timeDiff":0}}
]);
