19// TDatime //
20// //
21// This class stores the date and time with a precision of one second //
22// in an unsigned 32 bit word (e.g. 950130 124559). The date is stored //
23// with the origin being the 1st january 1995. //
24// //
25// This class has no support for time zones. The time is assumed //
26// to be in the local time of the machine where the object was created. //
27// As a result, TDatime objects are not portable between machines //
28// operating in different time zones and unsuitable for storing the //
29// date/time of data taking events and the like. If absolute time is //
30// required, use TTimeStamp. //
