1分钟
3600秒等于:
1小时
1秒=1000毫秒(ms)
古籍中的时间长度
佛教梵典《僧只律》这本书中记载著:
一刹那者为一念,二十念为一瞬,二十瞬为一弹指,二十弹指为一罗预,二十罗预为一须臾,一日一夜有三十须臾。
根据这段文字所推算出的具体时间:
一昼夜=30须臾=600罗预=12000弹指=240000瞬间=4800000刹那
因为一昼夜=86400秒,因此把每个单位换算成秒数,可以得到:
一“须臾”=2880秒(48分钟)
一“弹指”=7.2秒
一“瞬间”=0.36秒
一“刹那”=一“念”之间=0.018秒
1秒 等于1千毫秒
1豪秒等于1千微秒
1微秒等于1千纳秒
1纳秒等于1千皮秒
1皮秒等于1千飞秒
0.000 000 001 毫秒 = 1皮秒
0.000 001 毫秒 = 1纳秒
0.001 毫秒 = 1微秒
1000 毫秒 = 1秒
飞秒(femtosecond)1飞秒为千万亿分之一秒
Most CLX objects represent date and time values using a TDateTime value. In Delphi, TDateTime is a type that maps to a Double. In C++, the TDateTime class corresponds to the Delphi TDateTime type.
The integral part of a Delphi TDateTime value is the number of days that have passed since 12/30/1899. The fractional part of the TDateTime value is fraction of a 24 hour day that has elapsed.
Following are some examples of TDateTime values and their corresponding dates and times:
0 12/30/1899 12:00 am
2.75 1/1/1900 6:00 pm
-1.25 12/29/1899 6:00 am
35065 1/1/1996 12:00 am
To find the fractional number of days between two dates, simply subtract the two values, unless one of the TDateTime values is negative. Similarly, to increment a date and time value by a certain fractional number of days, add the fractional number to the date and time value if the TDateTime value is positive.
When working with negative TDateTime values, computations must handle time portion separately. The fractional part reflects the fraction of a 24-hour day without regard to the sign of the TDateTime value. For example, 6:00 am on 12/29/1899 is ?.25, not ? + 0.25, which would be ?.75. There are no TDateTime values between ? and 0.
上面的回答可能不是你要问的。
你是不是想问:如1.38小时=( )小时( )分?如果是,那这样算——
0.38小时=38/100≈3/60小时≈23分
∴:1.38小时=( 1 )小时(23)分
