RESULTS: The numeric type timing variance would be obtained in database with the way of variable chronometry. The timing would be kept as a document of textual form with the way of document chronometry. All the operations would be counted time with the above ways. CONCLUSION: EpiData has the function of counting time.

结果：变量计时法可以直接在原数据库中得到数值型计时变量，文件计时法则将计时结果另存为文本格式的文件。2种方法均能实现对每个变量、每条记录、每次操作数据库的数据录入过程进行计时。

METHODS: The data were input with EpiData, then the function of timing was come true through two methods of compiling control sequence code. The first way was variable chronometry, which sets up variance in database and installed the order of quality control. The second way was document chronometry. Timing results were wrote-in document drawing assistance from the function of writenote with EpiData.

运用EpiData进行数据录入，通过编写控制程序代码用2种方法实现计时功能，一是变量计时法，即在数据库中建立变量，通过设置质控命令达到计时目的；二是文件计时法，即借助EpiData的Writenote功能将计时结果写入备忘文件。
