title: Converting between timezones in C
body: <p>I need to convert time between timezones in C (on linux, so anything specific would do too).</p>
  
  <p>I know my current time, local and UTC, I have the offset of the target time.  I am trying to use mktime, gmtime, localtime and similar set of functions but still can't figure it out.</p>
  
  <p>Thanks in advance.</p>
