### 倒计时
|
|
|
|
:::warning
|
|
Suspend is tentative, it ** just pauses the countdown, not the time, because value points to a future time node **
|
|
|
|
If you need to add time to the original, please note that the overall time (the amount of time added and the original time) must be a ** future ** time node, otherwise it is still the end of the countdown
|
|
:::
|
|
:::demo Providing a future time via 'value' will enable the countdown function
