Datestamp format 2nd change in csv file (awk or sed)

I have a csv file formatted like this:

Code:
2014-08-21 18:06:26,A,B,12345,123,C,1232,26/08/14 18:07

and I'm trying to change it to MM/DD/YYYY HH:MM for both occurances.
I have got this:
Code:
awk -F, 'NR <=1 {print;next}{"date +%d/%m/%Y\" \"%H:%m -d\""$1 "\""| getline dte;$1=dte}1' OFS="," test.csv

This changes and formats the first occurance, but how do I convert the second one at the same time?

I'm also hitting this error
Code:
awk: cmd. line:1: (FILENAME=test.csv FNR=258) fatal: cannot create child process for `date +%d/%m/%Y" "%H:%m -d"2014-04-15 14:14:11"' (fork: Resource temporarily unavailable)

Is awk exhausting all my memory?

In fact, whilst that command runs on one flavour of unix, it doesn't run on redhat :-(. The first field is null.


Thanks in advance

For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
