QS:Time limit warning message
From LimeSurvey Manual
Time limit warning message (time_limit_warning_message)
Description
If set up, it displays the text of the warning message which is displayed for a fixed period of time before a time limit expires. The default text is "Your time to answer this question has nearly expired. You have {TIME} remaining." {TIME} is replaced by a formatted description which represents the amount of time left (i.e. "30 seconds", "1 minute or 5 seconds"). This message only appears if the time_limit_warning attribute exists. You can set from the time_limit_warning attribute when the message (time_limit_warning_message) appears.
This question attribute is only applicable if the time limit setting is activated and you set some text in the time limit warning message field. This setting also exists for a second warning message.
Example
Attention: In {TIME} the time limit to answer question will expire.
