1. Why does @SYSINFO(WINBOOT) tack an AM or PM to the end of the result? (IE. 40:22:12:43 PM ) I assume that this means 40 Days 22 Hours 12 Minutes and 43 Seconds... Not sure what the PM is for.

2. Has anyone written a routine that will add/subtract time from the current datetime?

What I'm trying to do is subtract the result of @SYSINFO(WINBOOT) from the current datetime to get the datetime that the system was last booted.

AM and PM are used in some countries that use 12 hour time eg. Australia

AM refers to the mornin and PM to the afternoon

so 2:30PM is 2:30 in the afternoon or 14:40 in 24 hour time

i came across the same observation when i looked at @SYSINFO(WINBOOT) and like you could not work out why it was there - i concluded that it was there by error as i could not see any rational to include AM or PM to the string returned

TimeDate.dll can do those types of calculations...

Yes, it appears to use a time conversion routine that uses the Windows time format setting to determine the output format.

It seems to me it would be better for it to return the value as a floating point number of days. Then you could do math on it, or use @datetime() to format it whichever way you want it. Thoughts?

Is there a way to convert this to a floating point number?
