Originally created by @pingus-nikalex on GitHub (Feb 28, 2020).

I have date in format "yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZ"
have 2 different tables:
Pin
class PinEntity: NSManagedObject {

@NSManaged var categoryId:String
@NSManaged var color:String
@NSManaged var createdAt:Date
@NSManaged var ddeleted:Bool
@NSManaged var ddescription:String
@NSManaged var id:String
@NSManaged var name:String
@NSManaged var ownerId:String
@NSManaged var updatedAt:Date
@NSManaged var version:String
@NSManaged var type:String
@NSManaged var latitude:Double
@NSManaged var longitude:Double

}

and
SyncTable
class SyncDateEntity: NSManagedObject {

@NSManaged var tableName:String
@NSManaged var lastSyncDate:Date

}

After saving one date to this tables: Example Date:
▿ 2020-02-28 12:09:47 +0000

• timeIntervalSinceReferenceDate : 604584587.157463

I have different time in this tables:
pins has
▿ 2020-02-28 12:09:47 +0000

• timeIntervalSinceReferenceDate : 604584587.157463
  SyncTable has
  ▿ 2020-02-28 12:09:47 +0000
• timeIntervalSinceReferenceDate : 604584587.1570001
  This milliseconds very important because when I fetch pins - with

func getPinsForSync(lastSyncDate:Date, completion:(([PinEntity]?) -> ())?) {
let pinsEntity = try! dataStack.fetchAll(From().where(.updatedAt > lastSyncDate))
if(completion != nil) {
completion!(pinsEntity)
}
}
always fetching one last pin and we need to sync his. Not correct.
Can anybody help with this problem, because I don't any ideas how to fix this.

Can you show how you are setting the dates for PinEntity and SyncDateEntity?
