WithinPastMinutes

Check whether two TDateTimes are only a number of minutes apart.

Declaration

Source position: dateutil.inc line 270

function WithinPastMinutes(

  const ANow: TDateTime;

  const AThen: TDateTime;

  const AMinutes: Int64

):Boolean;

Arguments

ANow

  

First moment in time.

AThen

  

Second moment in time.

AMinutes

  

Number of minutes to check.

Function result

True if ANow and Athen are only AMinutes apart, false otherwise.

Description

WithinPastMinutes compares the timestamps ANow and AThen and returns True if the difference between them is at most AMinutes minutes apart, or False if they are further apart.

Remark: Since this function uses the MinutesBetween function to calculate the difference in Minutes, this means that fractional minutes do not count, and the fractional part is simply dropped, so for two dates actually 2 and a half minutes apart, the result will also be True
