Tokens can be cleaned up before expected

[ben-jacobs]

If the server time isn't set to UTC, then Tokens can be potentially cleaned up before expected (e.g. in +10:30 they effectively get cleaned up immediately. Changing DateTimeOffset.Now to DateTimeOffset.UtcNow appears to fix the problem.

Cheers Ben

private async Task ClearTokens()
        {
            try
            {
                Logger.Info("Clearing tokens");
                await options.Store.AsyncDatabaseCommands.DeleteByIndexAsync("TokenCleanupIndex",
                    new IndexQuery
                    {
                        Query = "Expires:[* TO \"" + DateTimeOffset.UtcNow.ToString("s") + "\"]"
                    }, new BulkOperationOptions
                    {
                        AllowStale = true
                    });
            }
            catch (Exception ex)
            {
                Logger.ErrorException("Exception cleaning tokens", ex);
            }
        }
