awk -remove pattern from file

I have a file like this - I want to remove the 2015 (or any four digit #) from column $4 so I can get:
Code:
Nov 05 1997 /ifs/inventory2/

for example. Im not sure how. Should I use an if statement with awk?

Code:
Jan 16 2015 23:45 /ifs/sql_file
Jan 16 2015 23:45 /ifs/sql_file
Nov 05 2015 1997 /ifs/inventory2/
Nov 05 2015 1997 /ifs/inventory8/
Nov 05 2015 1997 /ifs/inventory7/
Nov 05 2015 1997 /ifs/inventory6/
Nov 05 2015 1997 /ifs/inventory5/

What I have got is this:
Code:
/tmp/filez1 |gawk '{if ($4 ~/1997/) }

but I don't know how to remove the 2015
from the file when 1997 is present.


I don't want anything removed from lines that do not have 1997

Locale::Currency(3)					User Contributed Perl Documentation				       Locale::Currency(3)

NAME
Locale::Currency - standard codes for currency identification SYNOPSIS
use Locale::Currency; $curr = code2currency('usd'); # $curr gets 'US Dollar' $code = currency2code('Euro'); # $code gets 'eur' @codes = all_currency_codes(); @names = all_currency_names(); DESCRIPTION
The "Locale::Currency" module provides access to standard codes used for identifying currencies and funds, such as those defined in ISO 4217. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 4217 three-letter codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying currencies. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $curr = code2currency('usd','alpha'); $curr = code2currency('usd',LOCALE_CURR_ALPHA); The codesets currently supported are: alpha, LOCALE_CURR_ALPHA This is a set of three-letter (uppercase) codes from ISO 4217 such as EUR for Euro. Two of the codes specified by the standard (XTS which is reserved for testing purposes and XXX which is for transactions where no currency is involved) are omitted. This is the default code set. num, LOCALE_CURR_NUMERIC This is the set of three-digit numeric codes from ISO 4217. ROUTINES
code2currency ( CODE [,CODESET] ) currency2code ( NAME [,CODESET] ) currency_code2code ( CODE ,CODESET ,CODESET2 ) all_currency_codes ( [CODESET] ) all_currency_names ( [CODESET] ) Locale::Currency::rename_currency ( CODE ,NEW_NAME [,CODESET] ) Locale::Currency::add_currency ( CODE ,NAME [,CODESET] ) Locale::Currency::delete_currency ( CODE [,CODESET] ) Locale::Currency::add_currency_alias ( NAME ,NEW_NAME ) Locale::Currency::delete_currency_alias ( NAME ) Locale::Currency::rename_currency_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Currency::add_currency_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Currency::delete_currency_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
