Good point, it might happen ..., based on the OP's actual files, one file seems to have sentences in one language, and the other file their respective english translations, so the chances of having a double time line, I think are small.

Quote:
In such a structure the time line is always the second field.
What happens if there are other records in between the first field and the time line ( not always a fixed field ) ? Maybe, this is not the case, but what if the records are not multilined ?
Codes can also be modified again to fit a particular situation ..., anyway I think the OP has a few options to choose from Smilie.

NAME
fwtmp, wtmpfix - manipulate connect accounting records SYNOPSIS
/usr/lib/acct/fwtmp [-ic] /usr/lib/acct/wtmpfix [file...] DESCRIPTION
fwtmp reads from the standard input and writes to the standard output, converting binary records of the type found in /var/adm/wtmpx to formatted ASCII records. The ASCII version is useful when it is necessary to edit bad records. wtmpfix examines the standard input or named files in utmpx format, corrects the time/date stamps to make the entries consistent, and writes to the standard output. A hyphen (-) can be used in place of file to indicate the standard input. If time/date corrections are not performed, acctcon(1M) will fault when it encounters certain date-change records. Each time the date is set, a pair of date change records are written to /var/adm/wtmpx. The first record is the old date denoted by the string "old time" placed in the line field and the flag OLD_TIME placed in the type field of the utmpx structure. The second record speci- fies the new date and is denoted by the string new time placed in the line field and the flag NEW_TIME placed in the type field. wtmpfix uses these records to synchronize all time stamps in the file. In addition to correcting time/date stamps, wtmpfix will check the validity of the name field to ensure that it consists solely of alphanu- meric characters or spaces. If it encounters a name that is considered invalid, it will change the login name to INVALID and write a diag- nostic to the standard error. In this way, wtmpfix reduces the chance that acctcon will fail when processing connect accounting records. OPTIONS
-ic Denotes that input is in ASCII form, and output is to be written in binary form. FILES
