illustrate

DateDiff function can be used to determine the specified number of time intervals between two dates. For example, you can use DateDiff to calculate the number of days between two dates, or to calculate the number of weeks from today to the end of the year.

To calculate the number of days difference between date1 and date2, you can use "days in a year" (y) or "day" (d). When interval is the "day of the week" (w), DateDiff returns the number of weeks in a two-day period. If date1 is a Monday, DateDiff counts the number of Mondays until date2. This number contains date2 but not date1. However, if interval is "weeks" (ww), the DateDiff function returns the number of "calendar weeks" in the two-day period. Obtained by counting the number of Sundays between date1 and date2. If date2 happens to be a Sunday, date2 will also be added to the count result of DateDiff; but whether date1 is a Sunday or not, it will not be included.

If date1 comes later than date2, the return value of the DateDiff function is a negative number.

The firstdayofweek parameter affects the results calculated using the time interval notation "W" or "WW".

If date1 or date2 is a date literal, the specified year becomes a fixed part of that date. However, if date1 or date2 is enclosed in double quotes (" ") and the year is omitted, the current year is inserted into the code each time the expression date1 or date2 is evaluated. This allows you to write program code that applies to different years.

When calculating the year difference between December 31st and January 1st of the next year, DateDiff returns 1 to indicate a year difference, although it is actually only a day difference.

How to use the Timer function in ASP

'This is the script execution time, the default is 90 seconds, it needs to be longer, otherwise the program will be interrupted after 90 seconds'3600 is one hour

Server.ScriptTimeOut=3600

set obj=server.createobject("timer.sleep")

'Parameter 1000 means the thread hangs for one second, you can set it at will

obj.setup=1000

do while true

response.write "("right(Time,8)") Hello, the current count value is "application("time_count")

＂
　　

obj.sleeptime

application(＂time_count＂)=application(＂time_count＂) 1

If Not Response.IsClientConnected Then

set obj=nothing

session.abandon

End If

loop
