Timer Resume Functionality for multiple timers

[amaheshwari-systango]

Hi I have a list of multiple timers where a user can select which timer he wishes to resume from a list of timers.

user 1: test,
time accrued: 5 seconds

user 2: test 2,
time accrued: 10 seconds
........
How to set timer directive which is running to make it resume from user 1 time & resume from user 2 when i select user 2 time.

start-time attribute isn't working can you explain how to achieve this.

how can i resume my timer from a predefined time from my controller because i'm using a one single timer that will record and push events according to the list item selected. The mutilple timer example doesn't works for me because it is using different timers and not a single timer directive.
