Class Description

                                                                      
 TDatime                                                              
                                                                      
 This class stores the date and time with a precision of one second   
 in an unsigned 32 bit word. The date is stored with the origin being 
 the 1st january 1995. See also class TStopwatch.                     
                                                                      


TDatime()
 Create a TDatime and set it to the current time.

TDatime(Int_t date, Int_t time)
 Create a TDatime and set it to the specified date and time.
 See Set() about the date, time format.

TDatime(Int_t year, Int_t month, Int_t day, Int_t hour, Int_t min, Int_t sec)
 Create a TDatime and set it to the specified year, month,
 day, time, hour, minute and second. See Set() about the format.

TDatime(const char *sqlDateTime)
 Expects as input a string in SQL date/time compatible format, like:
 yyyy-mm-dd hh:mm:ss.

const char* AsString() const
 Return the date & time as a string (ctime() format).
 Copy result because it points to a statically allocated string.

const char* AsSQLString() const
 Return the date & time in SQL compatible string format, like:
 1997-01-15 20:16:28. The returned string buffer is static and
 will bew reused.

UInt_t Convert() const
 Convert fDatime from TDatime format to the standard time_t format.

void Copy(TDatime &datime)
 Copy this to datime.

void FillBuffer(char *&buffer)
 Encode Date/Time into buffer, used by I/O system.

Int_t GetDate() const
 Return date in form of 19971224 (i.e. 24/12/1997)

Int_t GetTime() const
 Return time in form of 123623 (i.e. 12:36:23)

void Print(Option_t *) const
 Print date and time.

void ReadBuffer(char *&buffer)
 Decode Date/Time from output buffer, used by I/O system.

void Set()
 Set Date/Time to current time as reported by the system.
 Date and Time are encoded into one single unsigned 32 bit word.
 Date is stored with the origin being the 1st january 1995.
 Time has 1 second precision.

void Set(Int_t date, Int_t time)
 Set date and time. Data must be in format 980418 or 19980418 and time in
 224512 (second precision). The date must
 be >= 950101.
 For years >= 2000, date can be given in the form 20001127 or 1001127
 internally the date will be converted to 1001127

void Set(Int_t year, Int_t month, Int_t day, Int_t hour, Int_t min, Int_t sec)
 Set date and time. Year may be xx where 95 <= xx <= 199 (199 being 2099).
 The year must be >= 1995.

void Streamer(TBuffer &b)
 Stream a object of type TDatime.

void GetDateTime(UInt_t datetime, Int_t &date, Int_t &time)
 Static function that returns the date and time
 Date is returned in the format 950223  February 23 1995.
 Time is returned in the format 102459 10h 24m 59s.
