Bug: Chromium timestamps are wrong

[stevenlele]

The start time should be 1601/1/1 00:00 UTC instead of local time, so all timestamps are 8 hours early if you are in UTC+8 timezone.

On macOS, the timestamps are 8h 5m 43s 0ms early in UTC+8 timezone. Didn't figure out the cause.

Should just do epoch -= 11644473600000000.

HackBrowserData/utils/typeutil/typeutil.go

Lines 42 to 53 in ecb8db1

	func TimeEpoch(epoch int64) time.Time {
	maxTime := int64(99633311740000000)
	if epoch > maxTime {
	return time.Date(2049, 1, 1, 1, 1, 1, 1, time.Local)
	}
	t := time.Date(1601, 1, 1, 0, 0, 0, 0, time.Local)
	d := time.Duration(epoch)
	for i := 0; i < 1000; i++ {
	t = t.Add(d)
	}
	return t
	}

Note: the timestamp was correct pre-v0.4.x:

HackBrowserData/utils/utils.go

Lines 43 to 54 in 38a40cb

	func TimeEpochFormat(epoch int64) time.Time {
	maxTime := int64(99633311740000000)
	if epoch > maxTime {
	return time.Date(2049, 1, 1, 1, 1, 1, 1, time.Local)
	}
	t := time.Date(1601, 1, 1, 0, 0, 0, 0, time.UTC)
	d := time.Duration(epoch)
	for i := 0; i < 1000; i++ {
	t = t.Add(d)
	}
	return t
	}

To identify export data generated pre-v0.4.x, the format was "...Z" instead of "...+08:00".
