# WithinPastMinutes

Check whether two TDateTimes are only a number of minutes apart

## Declaration

Source position: dateutil.inc line 261

 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

 WithinPastYears Check whether two TDateTimes are only a number of years apart WithinPastMonths Check whether two TDateTimes are only a number of months apart WithinPastWeeks Check whether two TDateTimes are only a number of weeks apart WithinPastDays Check whether two TDateTimes are only a number of days apart WithinPastHours Check whether two TDateTimes are only a number of hours apart WithinPastSeconds Check whether two TDateTimes are only a number of seconds apart WithinPastMilliSeconds Check whether two TDateTimes are only a number of milliseconds apart

## Example

Procedure Test(ANow,AThen : TDateTime; AMinutes : Integer);

begin
Write(DateTimeToStr(AThen),' and ',DateTimeToStr(ANow));
Write(' are within ',AMinutes,' Minutes: ');
Writeln(WithinPastMinutes(ANow,AThen,AMinutes));
end;
