|

<div><p>The result of subtracting one time (TIME2) from another (TIME1)
|
|||
|
|
is a time duration that specifies the number of hours, minutes, and seconds
|
|||
|
|
between the two times.</p>
|
|||
|
|
<div class="p">The data type of the result is DECIMAL(6,0). If TIME1 is greater than or
|
|||
|
|
equal to TIME2, TIME2 is subtracted from TIME1. If TIME1 is less than TIME2,
|
|||
|
|
however, TIME1 is subtracted from TIME2, and the sign of the result is made
|
|||
|
|
negative. The following procedural description clarifies the steps involved
|
|||
|
|
in the operation RESULT = TIME1 - TIME2. <div class="fignone"><p>If %SECOND(TIME2) <= %SECOND(TIME1) ;<br />
|
|||
|
|
then %SECOND(RESULT) = %SECOND(TIME1) - %SECOND(TIME2).<br />
|
|||
|
|
<br />
|
|||
|
|
If %SECOND(TIME2) > %SECOND(TIME1) ;<br />
|
|||
|
|
then %SECOND(RESULT) = 60 + %SECOND(TIME1) - %SECOND(TIME2). ;<br />
|
|||
|
|
%MINUTE(TIME2) is then incremented by 1.<br />
|
|||
|
|
<br />
|
|||
|
|
If %MINUTE(TIME2) <= %MINUTE(TIME1) ; <br />
|
|||
|
|
then %MINUTE(RESULT) = %MINUTE(TIME1) - %MINUTE(TIME2).<br />
|
|||
|
|
<br />
|
|||
|
|
If %MINUTE(TIME2) > %MINUTE(TIME1) ; <br />
|
|||
|
|
then %MINUTE(RESULT) = 60 + %MINUTE(TIME1) - %MINUTE(TIME2). ; <br />
|
|||
|
|
%HOUR(TIME2) is then incremented by 1.<br />
|
|||
|
|
<br />
|
|||
|
|
%HOUR(RESULT) = %HOUR(TIME1) - %HOUR(TIME2).</p>

<p>For example, the result of %TIME('11:02:26') - '00:32:56' is 102930 (a
|

|
|
duration of 10 hours, 29 minutes, and 30 seconds).</p>
