Ring/教程/日期和时间
< Ring
在本章中，我们将学习有关日期和时间函数的信息。
语法
Clock() ---> The number of clock ticks from program start示例
See "Calculate performance" + nl
t1 = clock()
for x = 1 to 1000000 next
see clock() - t1
我们可以使用 Time() 函数获取系统时间。
示例
See "Time : " + time()
我们可以使用 Date() 函数获取日期。
语法
Date() ---> String represent the date "dd/mm/yyyy"示例
See "Date : " + date() # Date : 24/05/2015
我们可以使用 TimeList() 函数打印日期和时间信息。
语法
TimeList() ---> List contains the time and date information.下表列出了这些项目。

See TimeList()示例
See "Day Name : " + TimeList()[2] # Sunday示例
See "Month Name : " + TimeList()[4] # May
语法
AddDays(cDate,nDays) ---> Date from cDate and after nDays示例
cDate = date()
see cDate + nl # 24/05/2015
cDate = adddays(cDate,10)
see cDate + nl # 03/06/2015
语法
DiffDays(cDate1,cDate2) ---> number of days (Date1 - Date2)示例
cDate1 = date()
see cDate1 + nl # 24/05/2015
cDate2 = adddays(cDate1,10)
see cDate2 + nl # 03/06/2015
see "DiffDays = " + diffdays(cDate1,cDate2) + nl # -10
see "DiffDays = " + diffdays(cDate2,cDate1) + nl # 10
