Question

I wonder if, when you call something like that

time();

it returns the timestamp relatively to your time zone setting or to UTC ?
For example, when syncing two agents, that must be important to take care of it, doesn’t it ?

Answer 1

You are absolutely right that the time needs to be adjusted for users at different locations.

• First, you need to be able to know
  what timezone each agent is in, which you cannot really guess, but ask the client to include the info in the request.
• Then, depending on the language you
  are using, you can either call some
  function with the timezone offset as
  the parameter to get the adjusted time, or calculate the
  time yourself by adding
  60*60*1000*offset milliseconds to the
  UTC time.
