Error in date format
Contributor II
hi.
i am working with the data containing date and and text processing .
separately these processes are working well. but after joining these i get the error message for the variable "current" in which i am using date_now() to get the system date. but later i took date difference (date-of-post and current) by converting it into date to numerical.
the process is as follows:
THE CSV file consists of :
DateOfPost- polynomial( e.g. 12/10/2006)
sentimentText- text(e.g. "i have bought a new car last week.it is very good")
id- integer(e.g. 1,2,3,4....................)
XML file is as follows:

The date_now() function returns an object of type "Date time". Using this with the date_parse_custom() function will result in an error because this function is expecting a string containing the date.
