I have a timefield like;

```
[08/Feb/2017:07:09:47 +0000]

```

and I use the pattern in grok match like;

```
\[(?<date_and_time>%{MONTHDAY}/%{MONTH}/20%{YEAR}:%{HOUR}:?%{MINUTE}(?::?%{SECOND}) ZZZ)\]

```

which is giving me a grokparsefailure. Somebody kindly help me to fix this?  
Thank you.

"ZZZ" belongs in a date filter, not a grok filter. Replace it with a grok pattern that matches timezone offsets.
