0 a bomb containing a device that makes it explode at a particular time -- 定時炸彈
1 a situation that is likely to become difficult to deal with or control -- 潛在危險；隱患
By ignoring the wishes of their employees, the managers are setting/creating a time bomb for themselves. 忽視僱員的願望，管理人員等於是在給自己埋下／製造一顆定時炸彈。
The prison governors are sitting on a time bomb (= are having to deal with a bad situation that is likely to become difficult to deal with or control). 這些典獄長如同正坐在定時炸彈上。
