TIMER
The Timer internal function returns a "Real Number" with 5 decimal digits accuracy with the number of seconds elapsed since midnight, January 1, 1970.
- This starting point is obtained from the operating system so it is only as accurate as your system time.
This value is used internally by the pro filer to monitor performance, but may be used within programs to measure the time very accurately
The function works as far back as 4.1x.
Simple Example:
PRINT TIMER Returns: 1305192990.17052
The following example shows the timer value, and converts it to various units "Minutes" "Hours" "Years". It also shows the total time elapsed for this program. (It usually returns 0.0156004) With 1 Attempt.
00001 PRINT Newpage
00010 LET Tot_Time=Timer
00020 PRINT "Timer:",Tot_Time
00030 PRINT "Minutes:",Int(Tot_Time/60)
00040 PRINT "Hours:",Int(Tot_Time/(60*60))
00050 PRINT "Years:",(Tot_Time/(60*60*24*365))
00060 LET New_Time=Timer
00065 IF (New_Time-Tot_Time)=0 THEN LET Attempts+=1 : GOTO 60
00070 PRINT "Time Elapsed: (";Attempts+1;")",New_Time-Tot_Time
