WTMPX File corrupted

Hi All

I work on solaris 8, 9 and 10 platforms and have encountered an error which is my wtmpx files appear to be corrupted as all entries contain the date 1970 (the birth of unix).

Now this is obviously not the case, so my query is:

1 - Can the existing wtmpx files be manipulated to provide correct dates

2 - Is it possible to recreate the wtmpx files with historic data

3 - Is this a know fix or bug?

Many thanks for your anticipated support.

NAME
utmpx, wtmpx - utmpx and wtmpx database entry formats SYNOPSIS
#include <utmpx.h> /var/adm/utmpx /var/adm/wtmpx DESCRIPTION
The utmpx and wtmpx files are extended database files that have superseded the obsolete utmp and wtmp database files. The utmpx database contains user access and accounting information for commands such as who(1), write(1), and login(1). The wtmpx database contains the history of user access and accounting information for the utmpx database. USAGE
Applications should not access these databases directly, but should use the functions described on the getutxent(3C) manual page to inter- act with the utmpx and wtmpx databases to ensure that they are maintained consistently. FILES
/var/adm/utmpx user access and adminstration information /var/adm/wtmpx history of user access and adminstrative information SEE ALSO
