How to convert a date&time variable into a time variable

machete — Wed, 02 Oct 2013 13:20:40 GMT

Dear all

I am trying to convert a date variable of the below format:

“05/01/201208:45:24”

(informat is DATETIME21.)

Using this command:

newtime=substr(Last_Modification_Date,11,9);

as I would like to have only hh:mm:ss

however with the above command i do not receive result:

‘.’

do you have an idea why this code does not
work?

Many thanks in advance for the support

Best

Hello Jagadish,

i am traying to ammend your code as I need to execute the code for the whole dataset, could you tell me where the mistake is in your opinion:

data match2.eurodailynew;

set match2.eurodaily;

input LastModificationDate $18.;

time=substr(LastModificationDate,11,8);

cards;

thanks

i treid this one

data match2.eurodailynew;

set match2.eurodaily;

LastModificationDate=datetime();

time=timepart(LastModificationDate);

run;

but then the time variable delivers a number instead of hh:mm:ss, how can i reformat this?

Thnx

Neo

Please try to use the time8. format

data eurodailynew;

set match2.eurodaily;

LastModificationDate=datetime();

time=timepart(LastModificationDate);

format time time8.;

run;

Thanks,

Hi I used the code you proposed, it just converted the original time variable to the current date today:

what was before e.g 06JAN2012:11:57:06.00

now is : 02OCT2013:17:43:02.95

there should be some mistake somewhere or?

Hi, could you please let me know the variable from match2.eurodaily from which you want to take only the timepart.

As an example consider that you have a variable name x with datetime data. the use the below code

data eurodailynew;

set match2.eurodaily;

LastModificationDate=input(x,datetime18.);

time=timepart(LastModificationDate);

format time time8.;

run;

Please try this and let me know if there is any problem.

Thanks,

Jagadish

the variable is called 'lastmodificationdate', below an example record:

'06JAN2012:11:57:06.00'

it has the following format: DATETIME21.2

the code you provided does still not work

i also tried to ammend it but it still does not work:

data match2.eurodailynew;

set match2.eurodaily;

newdate=input(LastModificationDate,datetime18.);

time=timepart(newdate);

format time time8.;

run;

Post the results from proc contents from your data please, and the code or log. TimePart should work, unless you have a character variable or are doing something else incorrectly.

proc contents data=match2.eurodaily;

run;

data match2.eurodailynew;

set match2.eurodaily;

newdate=input(LastModificationDate,datetime18.);

time=timepart(LastModificationDate);

time2=timepart(newdate);

format time time2 time8.;

run;

Below thw proc contents. Your code worked and converted the time variable but the newdate variable is empty, should it be like that?

lastmodificationdate is already a datetime and thus stored as numeric. Hence, input(lastmodificationdate, datetime18.) won't work as it attempts to convert a string of the form "ddmmmyy:hh:mm:ss" into a numeric value representing the number of seconds since 01JAN1960:00:00:00 (which is what your variable already is).

Data Null had the appropriate answer, all you needed was to attribute an appropriate format to the newly created variable after using timepart.

data match2.eurodailynew;

set match2.eurodaily;

time=timepart(LastModificationDate);

format time time8.;

run;

Should do the appropriate conversion. All date, time and datetime format variables are stored internally as a numeric count. Either the number of days since 01jan1960, the number of seconds since 00:00:00.00 or the number of seconds since 01jan1960:00:00:00.00 respectively. Any new variable created from manipulation of these dates will return a numeric value with a similar count. You simply need to tell SAS that you want it to be represented as a date/time or datetime format via a format statement after creating the variable.
