--- title: "now" description: "Returns the current time." --- # now > Returns the current time. **This function is used by Ignition's Expression language.** ## Description Returns the current time. The host computer's system clock is used, meaning that if this expression is being evaluated in a running client, the computer running the client's system clock is used. This function is one of the few expression functions that will poll. If you do not specify a pollRate, it will default to 1,000ms. If you do not want this function to poll, use a poll rate of zero. ## Syntax `now([pollRate])` ### Parameters | Type | Parameter | Description | |---------|-------------|---------------------------------------------------------------------------------------| | Integer | `pollRate` | The poll rate in milliseconds to update the time. Defaults to 1,000 ms. [optional] | ### Returns **Date** - The current time, based on the host computer's system clock. If a poll rate is specified, the returned time will update at the given interval. ## Examples ```python title="Code Snippet" now() //Returns the current time, updates every second. ``` ```python title="Code Snippet" now(13000) //Returns the current time, updates every 13 seconds. ``` ```python title="Code Snippet" dateFormat(now(0), "MMM d, h:mm a") //returns a string representing the current time, formatted like "Feb 12, 9:54 AM". Does not update ```
