Detailed Description

Implementation of the system time. Every system using this library can inherit its own specific class and override the getSystemTime() - member-function. If not overridden (using the base class (this one :)), see WOscSystemTime::GetSystemTime() for details.

Member Function Documentation

WOscTimeTag WOscSystemTime::GetSystemTime

(

)

const [virtual]

Returns the system time. When not overridden in a derived class, it returns largest time tag possible.

Returns:

Time representing the current system time.

Remarks:

Time tags are represented by a 64 bit fixed point number. The first 32 bits specify the number of seconds since midnight on January 1, 1900, and the last 32 bits specify fractional parts of a second to a precision of about 200 picoseconds. This is the rep- resentation used by Internet NTP timestamps. The time tag value consisting of 63 zero bits followed by a one in the least signifigant bit is a special case meaning "immediately."
