When I use <ZDT> (Zulu date time) in my SK macro I get this for a date/time..
09/23/08 00:43 EST de W1RET sk
I don't know where the EST is coming from other than that is the time zone I am in although right now it is EDT. I would think it would be GMT or UTC or Z. The time and date shown are correct zulu time and dates.
If I change to <IZDT> (ZDT in iso-8601 format) I get this for a date/ time....

A bit long but it shows the time as Z and not EST. Again time and dates are correct for zulu time.
I wonder if <ZDT> is picking the time zone from the local PC clock?
