Careful: ${a} supposes that there is a variable *on the Test Plan level*
that is named a (e.g., created by a RegexExtractor or UserDefinedVariables).
Before Jmeter sends your BSH Script to the interpreter, it substitutes
all occurences of ${a} by the value of this Jmeter variable.
"int a=1" on the other hand creates a variable local to your BSH Script.
The two types of variables can't be mingled.
To manipulate Jmeter variables, use the vars object from BSH.
>From your earlier error logs, I assume time1 and time2 are actual Jmeter
variables. To loose the milliseconds, I suggest using them as strings,
chopping 3 characters using substr() or whatever that is in BSH and then
parse it to a long value.
