Why do you need to create it? I deleted it the last time it filled up the directory. What is the need for the file? Just wondering.

wtmpconvert
wtmpconvert(8) System Manager's Manual wtmpconvert(8)
NAME
wtmpconvert - Modify connect time accounting records from DIGITAL UNIX releases 4.0x and prior to new format
SYNOPSIS
/usr/lbin/wtmpconvert [-vnrp?h] input_file [output_file]
OPTIONS
Restore new format to old format. Verbose. Display lines while converting. Do not preserve contents of input file. Formatted print only.
Do not convert. (May be used with the -r option). Display usage message.
DESCRIPTION
The wtmpconvert command reads records from a connect time accounting file, such as /var/adm/wtmp, and converts the record format to the
updated struct utmp format. If no output file is specified or if the output file path is identical to the input file path, wtmpconvert
makes a backup copy of the original input file using the following algorithm: If filename.orig exists. Where n is a unique number.
The wtmpconvert command attempts to detect an input file that is in the wrong format (for example, input file is already a new format
file). A warning message is issued in this case, but conversion continues.
EXIT STATUS
Success. An error occurred.
EXAMPLES
To convert an old format accounting file to the new format: wtmpconvert /var/adm/wtmp.prev
Upon completion of this command, /var/adm/wtmp.prev will have been converted to the new format. The original /var/adm/wtmp.prev is
renamed to /var/adm/wtmp.prev.orig. To convert a wtmp file in new format to the old format: wtmpconvert -r /var/adm/wtmp
/var/adm/wtmp.old
FILES
Accounting header files that define the format for the login database file. The active login/logoff database files.
