now
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.
