Time Management Services

The ChorusOS operating system offers five time management services:

• Clock service (tick)

• Date service

• timeout service

• Timer service (TIMER)

• Virtual time and virtual timeout service (VTIMER)

The configuration of your ChorusOS operating system determines which services are available. Table 12-1 indicates which services are available for a given configuration:
