Owning Palette: Programming VIs and Functions
Requires: Base Development System. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Timing VIs and Functions to manipulate the speed at which an operation executes and to retrieve time and date information from the computer clock.
|Date/Time To Seconds||Converts a cluster of time values into a timestamp measured as the number of seconds that have elapsed since 12:00 a.m., Friday, January 1, 1904, Universal Time, assuming is DST is set to 1.|
|Elapsed Time||Indicates the amount of time that has elapsed since the specified start time.|
|Format Date/Time String||Displays a timestamp value or a numeric value as time in the format you specify using time format codes.
The following codes are some of the most commonly used time format codes: %c displays locale-specific date/time; time-related format codes include %X (locale-specific time), %H (hour, 24-hour clock), %I (hour, 12-hour clock), %M (minute), %S (second), %<digit>u (fractional seconds with <digit> precision), and %p (a.m./p.m. flag); date-related format codes include %x (locale-specific date), %y (year within century), %Y (year including century), %m (month number), %b (abbreviated month name), %d (day of month), and %a (abbreviated weekday name).
|Get Date/Time In Seconds||Returns a timestamp of the current time. LabVIEW calculates this timestamp using the number of seconds elapsed since 12:00 a.m., Friday, January 1, 1904, Universal Time.|
|Get Date/Time String||Converts a timestamp value or a numeric value to a date and time string in the time zone configured for the computer. The function interprets timestamp and numeric values as the time-zone-independent number of seconds that have elapsed since 12:00 a.m., Friday, January 1, 1904, Universal Time.|
|Seconds To Date/Time||Converts a timestamp value or a numeric value to a cluster of time values.|
|Tick Count (ms)||Returns the value of the millisecond timer.|
|Time Delay||Inserts a time delay into the calling VI.|
|Time Stamp Constant||Use the time stamp constant to pass a time and date value to the block diagram.|
|To Time Stamp||Converts a number to a timestamp.|
|Wait (ms)||Waits the specified number of milliseconds and returns the value of the millisecond timer. Wiring a value of 0 to the milliseconds to wait input forces the current thread to yield control of the CPU.|
|Wait Until Next ms Multiple||Waits until the value of the millisecond timer becomes a multiple of the specified millisecond multiple. Use this function to synchronize activities. You can call this function in a loop to control the loop execution rate. However, it is possible that the first loop period might be short. Wiring a value of 0 to the milliseconds multiple input forces the current thread to yield control of the CPU.|
