[Solved] EnvSub error "Parameter #2 invalid" PostVer1.1

[RobertL]

Code: Select all

a := A_Now
a -= 8, Hours	;Parameter #2 invalid.
MsgBox, % a
a += 8, Hours	;OK
MsgBox, % a

Code: Select all

a := A_Now
b:=8
a -=% b, Hours
MsgBox, % a	;Empty

Same error using EnvSub.
Could use a += -8, Hours.

TimeUnits
If present, this parameter directs the command to subtract Value from Var as though both of them are date-time stamps in the YYYYMMDDHH24MISS format.

EnvAdd TimeUnits: If present, this parameter directs the command to add Value to Var, treating Var as a date-time stamp in the YYYYMMDDHH24MISS format and treating Value as the integer or floating point number of units to add (specify a negative number to perform subtraction). http://ahkscript.org/docs/commands/EnvAdd.htm

EnvSub: TimeUnits ... To add or subtract a certain number of seconds, minutes, hours, or days from a timestamp, use EnvAdd (subtraction is achieved by adding a negative number). http://ahkscript.org/docs/commands/EnvSub.htm
