It builds on [TimeTextElement](/dbnetsoft/screenspro/controls/timetextelement.md); only the properties it adds are listed here. ## Properties | Name | Type | Description | | ------------------ | ------- | ----------------------------------------------------------------------------------------------------------- | | `UseInternalClock` | Boolean | Takes the time from the clock of the computer. Turn it off to read the time from `ComPort`. Default `true`. | | `Format` | String | Format the time is displayed in. Default `HH:mm:ss`. | | `ComPort` | String | Serial port the time is read from while `UseInternalClock` is off. Default `COM6`. | | `Baudrate` | int | Baud rate of that serial port. Default `9600`. | ## Blinking colon With the formats `HH:mm`, `hh:mm tt` and `GG:mm tt` the colon is replaced by a space every other second, so the clock blinks like a display board. ## Serial input Two line formats are recognised: | Line | Source | | ---------------------- | ----------------------------- | | `NNN.xxxxHH:MM:SS.zxx` | Display board, 20 characters. | | `HH:MM:ss.z` | PC timer, 10 characters. | If the port cannot be opened, this is written to the log once and not tried again, so check the log when the clock stays empty. ## Example ```xml ```
