Subject: fixup! Support time unit type (millisecond, microsecond)
X-Git-Tag: accepted/tizen/unified/20231205.171421^0
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F03%2F302103%2F7;p=platform%2Fcore%2Fmultimedia%2Ftrackrenderer.git

fixup! Support time unit type (millisecond, microsecond)

refactoring by introducing immutable TimeConverter class to handle
various time conversion.
