The time zone that most closely aligns with the post time displayed in the phone screen shot is northeastern Australia, Vladivostok Russia, and Guam.
That could be significant. or it could be nothing. I don't know how prevalent the use of 24 hour clocks is in Australia or Russia but there is a large contingent of US military stationed on Guam who certainly use 24 hour time.
