using kernel timer to wake do something a few times a day

Question

Hi, 
 I need my NRF9160 to do some task multiple times a day. 
 i.e. 
 in 8:25, 9:40,12:30,... 
 each day. 
 would it be considered good practice to use kernel timers to for each times (as stated above) , with a 24 hour time period? 
 is there a limit on the number of timers? 
 
 Thanks!

Hi Moshe, What are this "tasks"? Sending data via LTE or just reading sensor data ? 
 Here is some extracts from the Timer documentation . 
 
 Suggested Uses 
 
 Use services based on the system clock for time-based processing that does not require high precision, such as timer objects or Thread Sleeping . 
 Use services based on the hardware clock for time-based processing that requires higher precision than the system clock can provide, such as Busy Waiting or fine-grained time measurements. 
 
 NOTE : The high frequency of the hardware clock, combined with its 32-bit size, means that counter rollover must be taken into account when taking high-precision measurements over an extended period of time.
