The TTimeStamp encapsulates seconds and ns since EPOCH.

This extends (and isolates) struct timespec

struct timespec
   {
      time_t   tv_sec;   // seconds
      long     tv_nsec;  // nanoseconds
   }
time_t seconds is relative to Jan 1, 1970 00:00:00 UTC

No accounting of leap seconds is made.

Due to ROOT/CINT limitations TTimeStamp does not explicitly hold a timespec struct; attempting to do so means the Streamer must be hand written. Instead we have chosen to simply contain similar fields within the private area of this class.

NOTE: the use of time_t (and its default implementation as a 32 int) implies overflow conditions occurs somewhere around Jan 18, 19:14:07, 2038. If this experiment is still going when it becomes significant someone will have to deal with it.

Constructor & Destructor Documentation

◆ TTimeStamp() [1/6]

TTimeStamp::TTimeStamp ( )

Default ctor.

Create a TTimeStamp and set it to the current time (as best possible). The nanosecond part is faked so that subsequent calls simply add 1 to ensure that sequential calls are distinct (and sortable).

Definition at line 95 of file TTimeStamp.cxx.

◆ TTimeStamp() [2/6]

◆ TTimeStamp() [4/6]

TTimeStamp::TTimeStamp	(	UInt_t	year,
		UInt_t	month,
		UInt_t	day,
		UInt_t	hour,
		UInt_t	min,
		UInt_t	sec,
		UInt_t	nsec = `0`,
		Bool_t	isUTC = `kTRUE`,
		Int_t	secOffset = `0`
	)

Create a TTimeStamp and set it to the specified year, month, day, time, hour, minute, second and nanosec.

If !isUTC then it is assumed to be the standard local time zone.

If local time is PST then one can use

TTimeStamp(year,month,day,hour,min,sec,nsec,kFALSE,0);

or

Int_t secOffset = 8*60*60;

TTimeStamp timeStamp(year,month,day,hour,min,sec,nsec,kTRUE,8*60*60);

Definition at line 115 of file TTimeStamp.cxx.

◆ TTimeStamp() [5/6]

TTimeStamp::TTimeStamp	(	UInt_t	date,
		UInt_t	time,
		UInt_t	nsec,
		Bool_t	isUTC = `kTRUE`,
		Int_t	secOffset = `0`
	)

Create a TTimeStamp and set it to the specified date, time, nanosec.

If !isUTC then it is assumed to be the standard local time zone.

Warning: Watch out! C++ overload resolution often chooses the constructor TTimeStamp(UInt_t tloc, Bool_t isUTC, Int_t secOffset, Bool_t dosDate) instead of this one. Your best bet is to explicitly pass UInt_t values instead of Int_t values. When calling with integer literals, pass for instance
TTimeStamp timeStamp(20150610u,80448u,0u)
to disambiguate.

◆ TTimeStamp() [6/6]

TTimeStamp::TTimeStamp	(	UInt_t	tloc,
		Bool_t	isUTC = `kTRUE`,
		Int_t	secOffset = `0`,
		Bool_t	dosDate = `kFALSE`
	)

Create a TTimeStamp and set it to tloc which must be a time_t value returned by time().

This value is the number of seconds since the EPOCH (i.e. 00:00:00 on Jan 1m 1970). If dosDate is true then the input is a dosDate value.

◆ AsGAST()

Double_t TTimeStamp::AsGAST ( Double_t UT1Offset = 0 ) const

Return Greenwich apparent sidereal time (GAST) in hour-angle.

Return value will always be between 0 and 24 (hours). Sidereal time is most accurately calculated from UT1. If fSec and fNanoSec are in UTC (which they are by default), the optional argument UT1Offset can be supplied (in milliseconds). If UT1Offset is not supplied, conversion has maximum error of 1s.

Return value will always be between 0 and 24 (hours). Sidereal time is most accurately calculated from UT1. If fSec and fNanoSec are in UTC (which they are by default), the optional argument UT1Offset can be supplied (in milliseconds). If UT1Offset is not supplied, conversion has maximum error of 1s.

Definition at line 214 of file TTimeStamp.cxx.

◆ AsString()

const Char_t * TTimeStamp::AsString ( const Option_t * option = "" ) const

Return the date & time as a string.

Result is pointer to a statically allocated string. User should copy this into their own buffer before calling this method again.

Option "l" returns it in local zone format (can be applied to default or compact format).

Default format is RFC822 compliant:

"Mon, 02 Jan 2001 18:11:12 +0000 (GMT) +999999999 nsec"

"Mon, 02 Jan 2001 10:11:12 -0800 (PST) +999999999 nsec"

Option "c" compact is (almost) ISO 8601 compliant:

"2001-01-02 18:11:12.9999999999Z"
"2001-01-02 10:11:12.9999999999-0800" if PST
- uses "-" as date separator as specified in ISO 8601
- uses "." rather than preferred "," for decimal separator
- -HHMM is the difference between local and UTC (if behind, + if ahead).
The "-HHMM" is replaced with "Z" if given as UTC. To be strictly conforming it should use "T" instead of the blank separating the date and time.

Option "2" returns as {sec,nsec} integers.

Option "s" returns "2001-01-02 18:11:12" with an implied UTC, overrides "l" option.

Internally uses a circular list of buffers to avoid problems using AsString multiple times in a single statement.

◆ IsLeapYear() [1/2]

Bool_t TTimeStamp::IsLeapYear	(	Bool_t	inUTC = `kTRUE`,

Is the year a leap year.

The calendar year is 365 days long, unless the year is exactly divisible by 4, in which case an extra day is added to February to make the year 366 days long. If the year is the last year of a century, eg. 1700, 1800, 1900, 2000, then it is only a leap year if it is exactly divisible by

Therefore, 1900 wasn't a leap year but 2000 was. The reason for these rules is to bring the average length of the calendar year into line with the length of the Earth's orbit around the Sun, so that the seasons always occur during the same months each year.
