CVI时间表示格式

Absolute Date/Time Specifiers and Modifier
The following list describes the absolute date/time format string specifiers:
∙%H—Hour in 24-hour format, also known as military time. Valid values are 00–23. (小时:24小时制)
∙%I—Hour in 12-hour format. Valid values are 01–12. (12小时制) ∙%M—Minute, as an integer. Valid values are 00–59. (分,int型) ∙%S—Second, as an integer. Valid values are 00–59. （秒，int型）∙%n f—The fractional part of the seconds,（指定“秒”的小数位数）rounded to n digits of precision, where n is an integer between 1
and 20. If you do not specify a value for n, LabWindows/CVI uses
a default precision, which depends on how you use the format string.
If you are formatting a graph or strip chart axis, LabWindows/CVI uses the precision specified for the axis. If you are using
FormatDateTimeString, LabWindows/CVI uses 3 as the default number of digits.
∙%p—AM/PM indicator for a 12-hour clock. The language settings that the operating system uses affect the value used.（采用12小时制
时显示“上下午”）
∙%b—Abbreviated month name.（月份名的缩写）
∙%B—Full month name. （月份名的全写）
∙%m—Month, as an integer. Valid values are 01–12.（用01~12的形式显示月份）
∙%d—Day of the month, as an integer. Valid values depend on the month and year and range from 01 to 31.（一个月中的第几天01~31）∙%j—Day of the year, as an integer. Valid values are 001–366.
∙%a—Abbreviated weekday name. （一年中的第几天001~366）
∙%A—Full weekday name. （星期的全名）
∙%w—Weekday, as an integer. Valid values are 0–6, where Sunday is
0. （int型显示星期：0~6）
∙%U—Week of the year, as an integer, where Sunday is considered the first day of the week. Valid values are 00-53. （一年中的第几个
星期，以星期日为一个星期的第一天）
∙%W—Week of the year, as an integer, where Monday is considered the first day of the week. Valid values are 00-53. （一年中的第几个
星期，以星期一为一个星期的第一天）
∙%Y—Year with century, as an integer. （年份，int型，如：2001）∙%y—Year without century, as an integer. Valid values are 00–99.
（年份的缩写，int型：00~99）
∙%x—Date representation based on the language settings that the operating system uses.（采用和操作系统日期一样的格式显示日期）
∙%X—Time representation based on the language settings that the operating system uses. （采用和操作系统时间一样的格式显示时间）∙%c—Date and time representation based on the language settings that the operating system uses. （采用和操作系统时间和日期一样的
格式显示时间和日期）
∙%z, %Z—Time zone name or time zone abbreviation. （显示时区）∙%%—Percent sign.（%）
用于：FormatDateTimeString (double dateTime, char formatString[], char outputBuffer[],
int outputBufferSize);
LabWindows/CVI also supports the # modifier, which indicates to remove leading zeros. For example, if LabWindows/CVI displays %S as 04 for a particular data value, LabWindows/CVI displays %#S as 4 for that data value.
Relative Date/Time Specifiers and Modifiers
The following list describes the relative date/time format string specifiers:
∙%H—Number of hours since the reference point.
∙%M—Number of minutes since the reference point.
∙%S—Number of seconds since the reference point.
∙%n f—The fractional part of the seconds since the reference point, rounded to n degrees of precision, where n is an integer between
1 and 20. If you do not specify a value for n, LabWindows/CVI uses
the precision specified for the graph or strip chart axis.
∙%X—Time since the reference point, based on the language settings that the operating system uses.
∙%d—Number of days since the reference point.
LabWindows/CVI also supports the following modifiers:
∙#—The # symbol indicates to remove any leading zeros. For example, if LabWindows/CVI displays %S as 04 for a particular data value, LabWindows/CVI displays %#S as 4 for that data value.
∙@—The @ symbol indicates to restrict overflow. For example, if 70 seconds have elapsed since the reference point and you specify %S as the format string, the axis displays 70. However if you
specify %@S as the format string, the axis displays 10. The seconds count starts over at 0 when the number of seconds reaches 60. The @ symbol restricts overflow for hours, minutes, and seconds only.
It modifies the largest applicable time unit in the format string.。
