Hi RudiC,

Yes indeed, I have checked all posts before replying back and clearly mentioned that none of the <scripts> worked because I tried all of them. The previous post had just one of the example as don't want to bump over with all outcomes as they all produced the same outcome.

Intention here is to resolve the issue to get experts advise to get issue resolved as pulling data with dates are extremely difficult due to presence of >=2 date formats in log file.


Below script result into invalid date
Code:
$ paste -d'\t\b' <(date -f <(sed 's/^<\|>.*$//g; s/,//2' file) +"%F %T") file | awk -F"\t" -vTS="$(date -d'30 min ago' +'%F %T')" '($1 > TS) {sub ("^" $1 FS, ""); print}'

date: invalid date `2019-03-04T11:03:16.576+0000: 1392540.816: [GC [PSYoungGen: 934720K-'
date: invalid date `\tat java.lang.reflect.Method.invoke(Method.java:606)'

DP(8)                                                                [nmh-1.5]                                                               DP(8)

NAME

       dp - parse dates 822-style

SYNOPSIS

       /usr/lib/mh/dp [-form formatfile] [-format string] [-width columns] [-version] [-help] dates ...

DESCRIPTION

       Dp  is  a  program that parses dates according to the ARPA Internet standard.  It also understands many non-standard formats, such as those
       produced by TOPS-20 sites and some UNIX sites using ctime(3).  It is useful for seeing how nmh will interpret a date.

       The dp program treats each argument as a single date, and prints the date out in the official 822-format.  Hence, it  is  usually  best  to
       enclose each argument in quotes for the shell.

       To  override  the  output  format  used by dp, the -format string or -format file switches are used.  This permits individual fields of the
       address to be extracted with ease.  The string is simply a format string and the file is simply a format file.  See  mh-format(5)  for  the
       details.

       Here is the default format string used by dp:

            %<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%>

       which  says  that  if an error was detected, print the error, a `:', and the date in error.  Otherwise, output the 822-proper format of the
       date.

FILES

       $HOME/.mh_profile          The user profile

PROFILE COMPONENTS

       None

SEE ALSO

       ap(8), Standard for the Format of ARPA Internet Text Messages (RFC-822)

DEFAULTS

       `-format' default as described above
       `-width' default to the width of the terminal

CONTEXT

       None

BUGS

       The argument to the -format switch must be interpreted as a single token by the shell that invokes dp.  Therefore, one must  usually  place
       the argument to this switch inside quotes.
