In the "Display Controls" you can quickly adjust the time of a dynamic (steppable) chart by using the "Time Stepping" facility. This is comprised of the "Time Step Interval" options, and the Step Forward ">", ">|" and Step Back "|<","<" buttons.
>> To set the time interval
 |
1)Click in the Time Step Interval itself and a pop-up dialog is displayed, as shown above with possible units of time being Seconds, Minutes, Hours, Days, Weeks, Months and Years . Click on the unit of time you want to use.
2)Once you have selected the unit of time enter the number of these units of time that will be stepped either forward or backward - up to a maximum of 100.
>> To step by the time interval
➢ Click any of the Step Forward or Step Backward buttons. The ">|" and "<|" only move the time one step at a time. The ">" and "<" step continuously through time.
•If only static (natal etc) charts are selected then a new transit chart will be placed in the outermost Ring, which will then be stepped. The time to step from will be taken from the innermost (Ring one) chart.
If there are no spare rings - for instance if there was a natal chart selected in all four rings - then you will be asked if you'd like to replace the outermost chart with a new transits chart which will be stepped.
•The date/time for the step is always controlled by the outermost chart. If any of the inner or middle chart(s) is also a dynamic chart (transits, secondary progressed or directed etc), then their dates are set to be the same as the outermost chart.
-OR-
➢ Alternatively open the Calendar by clicking on its icon 
in the display controls, and set the date you would like to directly jump to. This does two things at once. It...
a)sets the date and time of every displayed dynamic chart (transit, progressed charts etc).
b)becomes the new base date/time from which any further stepping (forwards or backwards) is related to.
>> Stepping by fixed time intervals versus calendar time intervals
When stepping a chart through time, if a timezone change occurred during the time step (e.g. DST) then one possibility is that the new chart’s clock time retains its previous local time even though the timezone has changed. This is one option and could be referred to as calendar-based time steps.
Another option, which Astro Gold does, is that in the situation above the local time is now adjusted to reflect the timezone change, while preserving the exact time step interval applied. This allows astrological/astronomical changes to progress consistently during chart stepping, regardless of DST changes, and can be referred to as exact-interval based (or fixed) time-steps.
