Return
the Datewith the offset added to it
Parameters
the start time
the offset in milliseconds to add to the time
A utility method that returns a date offset by the offset time passed in. Please note that the level of light during twilight is not affected by elevation, so if this is being used to calculate an offset before sunrise or after sunset with the intent of getting a rough "level of light" calculation, the sunrise or sunset time passed to this method should be sea level sunrise and sunset.
Return
the Date with the offset in milliseconds added to it, or null if time is null or offset is Long.MIN_VALUE
Parameters
the start time
the offset in milliseconds to add to the time.
