DATETIME

Top  Previous  Next

The DateTime library is written by Josef Franz Vögel. It extends the clock routines with date and time calculation.

 

 

The following functions are available:

 

DayOfWeek

Returns the day of the week

DayOfYear

Returns the day of the year

SecOfDay

Returns the second of the day

SecElapsed

Returns the elapsed Seconds to a former assigned time-stamp

SysDay

Returns a number, which represents the System Day

SysSec

Returns a Number, which represents the System Second

SysSecElapsed

Returns the elapsed Seconds to a earlier assigned system-time-stamp

Time

Returns a time-value (String or 3 Byte for Second, Minute and Hour) depending of the Type of the Target

Date

Returns a date-value (String or 3 Bytes for Day, Month and Year) depending of the Type of the Target

 

 

notice Date and time not to be confused with Date$ and Time$ !

 

The date starts at 1.1.2000 and valid from 2000 to 2099

If you wish to convert to NTP which starts at 1.1.1970, which is 30 years earlier, you need to subtract a value of 946684800

BASCOM DATE_TIME = NTP - 946684800

 

noticeMost of the Date and Time functions accept variables which must be in sequential memory order. Like bSec, bMin, bHour

When using DIM like this :  Dim bSec As Byte, bMin As Byte, bHour As byte , the variables will be in sequential order, but this might change in the future.

Better would be to be explicit :  Dim bSec as byte , bMin as byte at bSec + 1 , bHour as byte at bMin + 1

This will ensure that the bytes will be mapped in the right order.
