The time and time flow speed applicable to StellarWindow can be set by clicking the ‘Clock’ icon located on the toolbar.
Observation time setting
When the date and time setting dialog is opened, the digital clock appears indicating the
date and time (observation date and time) applicable to StellarWindow. The default date and
time correspond to those set in the PC and are displayed in the “Current time” field.
The ‘year,’ ‘month,’ ‘date,’ ‘hour,’ ‘minute’ and ‘second’ can be reset by clicking the triangle
marks located in the right side of the individual items located in the “Setting change”
field or numeric data can be input directly using the keyboard.
A Christian era year can be selected ranging from ancient times to far into the future. However,
selecting a year significantly different from the current time results in: 1) inaccurate
man-made satellite orbit calculations, 2) inaccurate planet orbit calculations and 3) inaccurate
star location identification in this order.
In the “Time flow speed” field, the time flow speed applicable to StellarWindow can be established
ranging from ‘0x’ to ‘9,999x’*1
