| Name| Description
| xref:BloombergLP/bsls/SystemTime/now.adoc[`now`] 
| Return the `TimeInterval` value representing the current system time according to the specified `clockType`. The returned value is the time interval between the reference time point defined for the supplied `clockType` (see {Reference Time Point}) and the current time.
| xref:BloombergLP/bsls/SystemTime/nowMonotonicClock.adoc[`nowMonotonicClock`] 
| Return the `TimeInterval` value representing the current system time according to the monotonic clock. The returned value is the time interval between the reference time point for the monotonic clock (see {Reference Time Point}) and the current time.
| xref:BloombergLP/bsls/SystemTime/nowRealtimeClock.adoc[`nowRealtimeClock`] 
| Return the `TimeInterval` value representing the current system time according to the real‐time clock. The returned value is the time interval between the reference time point for the real‐time clock (see {Reference Time Point}) and the current time.
