SbTime()SbTime(doublesec)SbTime(int32_tsec,longusec)SbTime(conststructtimeval*tv)
Constructors taking seconds, seconds and microseconds, or a structtimeval. NOTE that an integer
parameter will not automatically cast to a double to invoke the constructor taking seconds; that is,
SbTime(1) will result in a compilation error. SbTime(1.0) must be used instead. This is to avoid
errors in upgrading from an earlier release, in which SbTime(1) had different semantics. In future
releases, this distinction will be eliminated, and the effect of SbTime(1.0) and that of SbTime(1)
will be identical.
staticSbTimegetTimeOfDay()
Get the current time (seconds since Jan 1, 1970).
voidsetToTimeOfDay()
Set to the current time (seconds since Jan 1, 1970).
staticSbTimezero()
Get a zero time.
staticSbTimemax()
Get a time far, far into the future.
voidsetValue(doublesec)
Set time from a double (in seconds).
voidsetValue(int32_tsec,longusec)
Set time from seconds + microseconds.
voidsetValue(conststructtimeval*tv)
Set time from a structtimeval.
voidsetMsecValue(unsignedlongmsec)
Set time from milliseconds.
doublegetValue()const
Get time in seconds as a double.
voidgetValue(int32_t&sec,long&usec)const
Get time in seconds and microseconds.
voidgetValue(structtimeval*tv)const
Get time in a structtimeval.
unsignedlonggetMsecValue()const
Get time in milliseconds (for Xt).
SbStringformat(constchar*fmt="%S.%i")const
Convert to a string. The default format is seconds with 3 digits of fraction precision. fmt is a
character string that consists of field descriptors and text characters, in a manner analogous to
cftime(3C) and printf(3S). Each field descriptor consists of a % character followed by another
character which specifies the replacement for the field descriptor. All other characters are copied
from fmt into the result. The following field descriptors are supported:
% the `%' character
D total number of days
H total number of hours
M total number of minutes
S total number of seconds
I total number of milliseconds
U total number of microseconds
h hours remaining after the days (00-23)
m minutes remaining after the hours (00-59)
s seconds remaining after the minutes (00-59)
i milliseconds remaining after the seconds (000-999)
u microseconds remaining after the seconds (000000-999999)
The uppercase descriptors are formatted with a leading `—' for negative times; the lowercase
descriptors are formatted fixed width, with leading zeros. For example, a reasonable format string
might be "elapsed time: %M minutes, %s seconds". The default value of fmt, "%S.%i", formats the time
as seconds with 3 digits of fractional precision.
SbStringformatDate(constchar*fmt="%A,%D%r")const
Convert to a date string, interpreting the time as seconds since Jan 1, 1970. The default format gives
"Tuesday, 01/26/93 11:23:41 AM". See the cftime() reference page for explanation of the format string.
SbTimeoperator+(constSbTime&t0,constSbTime&t1)SbTimeoperator-(constSbTime&t0,constSbTime&t1)
Addition and subtraction of two times.
SbTime&operator+=(constSbTime&tm)SbTime&operator-=(constSbTime&tm)
Addition and subtraction of two times which modifies the time structure.
SbTimeoperator-()const
Unary negation.
SbTimeoperator*(doubles,constSbTime&tm)SbTimeoperator*(constSbTime&tm,doubles)SbTimeoperator/(constSbTime&tm,doubles)
Multiplication and division by scalar.
SbTime&operator*=(doubles)SbTime&operator/=(doubles)
Destructive multiplication and division by scalar.
doubleoperator/(constSbTime&tm)const
Division by another time.
SbTimeoperator%(constSbTime&tm)const
Modulus for two times (remainder when time1 is divided by time2).
intoperator==(constSbTime&tm)constintoperator!=(constSbTime&tm)const
Equality operators.
SbBooloperator<(constSbTime&tm)constSbBooloperator>(constSbTime&tm)constSbBooloperator<=(constSbTime&tm)constSbBooloperator>=(constSbTime&tm)const
Relational operators.
