deep sleep standard timer running

Is it possible to let the standard timer (0/1/2) run in deep-sleep. I think in the user manual is written no:

For a wireless application I need to track time. If possible with a resolution of 32us. Therefore I used the timer 0 with a external 32kHz crystal as RTC clock. The RTC clock is used in sleep-mode for the timer 0. But in deep-sleep this didn't work.

 

Do I have to use the RTC-Timer (Alarm), to keep track of time? 
I would like to have a 32kHz Timer in low-power mode meanwhile the RTC seems to be max 1kHz (wakeup-timer). 

 

Is there a solution for my question?
