Parse exception on SaveAsync()

Occasionally (about 1 in 6 times) when attempting to create then save a parseObject, I get the following exception thrown

at System.DateTime.ParseExact (System.String s, System.String[] formats, IFormatProvider provider, DateTimeStyles style) [0x00000] in :0 at System.DateTime.ParseExact (System.String s, System.String format, IFormatProvider provider, DateTimeStyles style) [0x00000] in :0 at System.DateTime.ParseExact (System.String s, System.String format, IFormatProvider provider) [0x00000] in :0 at Parse.ParseClient.ParseDate (System.String input) [0x00000] in :0 at Parse.ParseObject.MergeMagicFields (IDictionary`2 data) [0x00000] in :0 at Parse.ParseObject.MergeFromServer (IDictionary`2 data) [0x00000] in :0 at Parse.ParseObject.MergeAfterSave (IDictionary`2 result) [0x00000] in :0 at Parse.ParseObject+c__DisplayClass1f.b__1b (System.Threading.Tasks.Task`1 t) [0x00000] in :0 at System.Threading.Tasks.TaskActionInvoker+FuncTaskInvoke`2[System.Tuple`2[System.Net.HttpStatusCode,System.Collections.Generic.IDictionary`2[System.String,System.Object]],System.Threading.Tasks.Task`1[System.Tuple`2[System.Net.HttpStatusCode,System.Collections.Generic.IDictionary`2[System.String,System.Object]]]].Invoke (System.Threading.Tasks.Task owner, System.Object state, System.Threading.Tasks.Task context) [0x00000] in :0 at System.Threading.Tasks.Task.InnerInvoke () [0x00000] in :0 at System.Threading.Tasks.Task.ThreadStart () [0x00000] in :0

I am using .net parse version 1.3.1.

The code causing the error looks like this:

ParseObject po = new ParseObject( "Journey" );
po.ObjectId = journey.ID;
po["audioCount"] = journey.AudioFiles.Count;
po["locationPointCount"] = journey.LocationPoints.Count;
po["photoCount"] = journey.PhotoFiles.Count;
po["videoCount"] = journey.VideoFiles.Count;
po["startTime"] = journey.StartTime;
po["endTime"] = journey.EndTime;
po["notes"] = journey.Notes;
po["isInProgress"] = journey.IsInProgress;

po.AddRangeUniqueToList( "audioFiles", audioFiles );
po.AddRangeUniqueToList( "photoFiles", photoFiles );
po.AddRangeUniqueToList( "videoFiles", videoFiles );

po.ACL = new ParseACL(ParseUser.CurrentUser);
po["user"] = ParseUser.CurrentUser;

await po.SaveAsync();

Thanks for any help

Edit: Removing "startTime" and "endTime" from the ParseObject does not resolve the issue.

Edit: For the sake of more information, here is the disassembly of the "MergeMagicFields" method which appears to be causing the problem. The only paths that end up calling "ParseData" appear to be related to parses internal data.

internal virtual void MergeMagicFields( IDictionary<string, object> data )
{
    lock( this.mutex )
    {
        if( data.ContainsKey( "objectId" ) )
        {
            this.SetObjectIdInternal( data["objectId"] as string );
            this.hasBeenFetched = true;
            this.OnPropertyChanged( "IsDataAvailable" );
            data.Remove( "objectId" );
        }
        if( data.ContainsKey( "createdAt" ) )
        {
            this.CreatedAt = new DateTime?( ParseClient.ParseDate( data["createdAt"] as string ) );
            data.Remove( "createdAt" );
        }
        if( data.ContainsKey( "updatedAt" ) )
        {
            this.UpdatedAt = new DateTime?( ParseClient.ParseDate( data["updatedAt"] as string ) );
            data.Remove( "updatedAt" );
        }
        if( data.ContainsKey( "ACL" ) )
        {
            ParseACL parseACL = new ParseACL( data["ACL"] as IDictionary<string, object> );
            this.serverData["ACL"] = parseACL;
            this.AddToHashedObjects( parseACL );
            data.Remove( "ACL" );
        }
    }
}
