[ncl-talk] systemfunc("date")

[Kyle Griffin]

Although this is likely a minor detail in the example you posted, it
appears you want things in UTC (hence the Z at the end of the timestamp).
Joe's response only works if your computer defaults to UTC as its time
zone. Otherwise, date -u +....... will be necessary to ensure the command
works regardless of the local time setting.
