# CosTime_TimeService

### MODULE

CosTime_TimeService

### MODULE SUMMARY

This module implements the OMG CosTime::TimeService interface.

### DESCRIPTION

To get access to the record definitions for the structures use:
`-include_lib("cosTime/include/*.hrl").`

### EXPORTS

`universal_time(TimeService) -> Reply`

Types:

`TimeService = #objref`
`Reply = UTO | {'EXCEPTION", #'TimerService_TimeUnavailable'{}}`
`UTO = #objref`

This operation returns the current time and the Inaccuracy given when starting this application in a UTO. The time base is 15 october 1582 00:00. Comparing two time objects which use different time base is, by obvious reasons, pointless.

`new_universal_time(TimeService, Time, Inaccuracy, Tdf) -> UTO`

Types:

`TimeService = UTO = #objref`
`Time = Inaccuracy = ulonglong()`
`Tdf = short()`

This operation creates a new UTO object representing the time parameters given. This is the only way to create a UTO with an arbitrary time from its components. This is useful when using the Timer Event Service.

`uto_from_utc(TimeService, Utc) -> UTO`

Types:

`TimeService = UTO = #objref`
`Utc = #'TimeBase_UtcT'{time, inacclo, inacchi, tdf}`
`time = ulonglong()`
`inacclo = ulong()`
`inacchi = ushort()`
`tdf = short()`

This operation is used to create a UTO given a time in the Utc form.

`new_interval(TimeService, Lower, Upper) -> TIO`

Types:

`TimeService = TIO = #objref`
`Lower = Upper = ulonglong()`

This operation is used to create a new TIO object, representing the input parameters. If Lower is greater than Upper BAD_PARAM is raised.
