TTimeStamp Class Reference

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::TTimeStamp ( const timespec_t ts)
inline

Definition at line 91 of file TTimeStamp.h.

◆ TTimeStamp() [3/6]

TTimeStamp::TTimeStamp ( time_t  t,
Int_t  nsec 
)
inline

Definition at line 95 of file TTimeStamp.h.

◆ 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.

Definition at line 137 of file TTimeStamp.cxx.

◆ 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. If offset is supplied error can be reduced to us level. Values for UT1Offset can be found in IERS Bulletin B: ftp://ftp.iers.org/products/eop/bulletinb/format_2009/ Equation of the equinoxes is given by USNO: http://aa.usno.navy.mil/faq/docs/GAST.php

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 local apparent sidereal time (LAST) in hour-angle, given a longitude in degrees.

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.

◆ 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,
Int_t  secOffset = 0 
) const

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

  1. 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.

◆ MktimeFromUTC()

time_t TTimeStamp::MktimeFromUTC ( tm_t tmstruct)

Equivalent of standard routine "mktime" but using the assumption that tm struct is filled with UTC, not local, time.

This version ISN'T configured to handle every possible weirdness of out-of-range values in the case of normalizing the tm struct.

This version DOESN'T correctly handle values that can't be fit into a time_t (i.e. beyond year 2038-01-18 19:14:07, or before the start of Epoch).
