Answer 1

Я рекомендую делать это в двух -ступят как проект, а затем группа.

var millisecondsFromUTC = 8 * 60 * 60 * 1000; //PST is -8 hours from UTC 

db.Product.aggregate([ 
    { $project : { 
     consumeDateLocal: { 
      $subtract : [ "$Counting.consumeDate", millisecondsFromUTC ] 
     }, 
     fee: '$Counting.fee" } }, 
    { $group: { 
     _id: { 
      "tyear": { $year: "$consumeDateLocal" }, 
      "tMonth": { "$month": "$consumeDateLocal" },     
      "tDate": { "$dayOfMonth": "consumeDateLocal" } 
     }, 
     count: { 
      $sum: "$fee" 
     } 
    } } ], ...); 

Answer 2

Я делаю это так.

millisecondsFromUTC = 8 * 3600 * 1000 
Db.collection.aggreagte([ 
    {$match: query}, 
    { 
    $group: { 
    _id: { 
     $dateToString: { 
     format: "%Y-%m-%d", 
     date: {$add: ["$date", millisecondsFromUTC]} 
    }, 
    click: {$sum: '$click'}, 
    money: {$sum: {$divide: ['$money', 10000]}}, 
    pv: {$sum: '$pv'}, 
    req: {$sum: '$req'}, 
    date: {$last: '$date'} 
    } 
}]
