推荐答案

最简单的是有一个开始时间在测试开始时数据库中的字段中。然后，当他们刷新剩下的东西时，可以从开始时间计算出来。我假设'答案'和问题存储在某个db表中。

The simplest is to have a start time in a field in the database for when the test starts. then when they refresh what is left can be calculated from start time. I am assuming that the 'answers' and questions are being stored in a db table somewhere.
