How can we set default time in time element , suppose i want to set 08:00 by default in time element.
Set the Default Value as 08:00 in the Properties section of Time Element. getVal() function can also be used in Default Value if you want to pick data from any path. The time format must always be in hh:mm

Can we show time in HH:MM:SS format also in time element? Through any way?
In vFlow, the Time element shows hh:mm time picker by default
If the user specifies hh:mm:ss time in the default value then the time picker will display seconds too.
Okay @ShraddhaDhoke Thankyou for the info…
@ShraddhaDhoke, I want to restrict the user that he/she should not enter/select the greater than specified time. How can i do that.
@Shubhamkumar1 You can add validation on Time element. This will highlight the Time field in red to indicate that the field is not valid.
Here, Max Time validation of 20:00 is set on the element.
Thanks @ShraddhaDhoke. It will helps a lot.
