 FFMPEG 4.2.1 Windows Build

 ffmpeg ^
 -rtsp_transport tcp ^
 -i rtsp://..... ^
 -f image2 ^
 -vf fps=fps=1 ^
 -strftime 1 ^
 "test\%%Y%%m%%d%%H%%M%%S%%z.jpg"

 image2 encoder states strftime is supported. However using the %z option
 produces timezone name '%Z' and NOT the numeric offset for the timezone.

 This parameter is not working properly.
 %z     The +hhmm or -hhmm numeric timezone (that is, the hour and
               minute offset from UTC). (SU)

 I also tested and NOTE that %s (epoch) is not supported.

 IDEALLY there would be an OPTION so support UTC time.
