This page describes the possible content of a CZML document or stream. Please read CZML Structure for an explanation of how a CZML document is put together.

Initial settings for a simulated clock when a document is loaded. The start and stop time are configured using the interval property.

Interpolatable: no

Examples:

{
    "clock": {
        "interval": "2012-03-15T10:00:00Z/2012-03-16T10:00:00Z",
        "currentTime": "2012-03-15T10:00:00Z",
        "multiplier": 60,
        "range": "LOOP_STOP",
        "step": "SYSTEM_CLOCK_MULTIPLIER"
    }
}

currentTime - Time

The current time, specified in ISO8601 format.

multiplier - number

The multiplier. When step is set to TICK_DEPENDENT, this is the number of seconds to advance each tick. When step is set to SYSTEM_CLOCK_DEPENDENT, this is multiplied by the elapsed system time between ticks. This value is ignored in SYSTEM_CLOCK mode.

Default: 1.0

range - ClockRange

The behavior when the current time reaches its start or end times.

Default: LOOP_STOP

step - ClockStep

How the current time advances each tick.

Default: SYSTEM_CLOCK_MULTIPLIER
