Here is an example:
KCOS 120054Z 18013KT 10SM CLR 01/M10 A2987 RMK AO2 SLP160 T00111100 $
This is from ASXP KCOS 241854Z 33020G40KT 10SM SCT050 BKN080 BKN230 00/M07 A2988 RMK AO2 PK WND 33044/1810 SLP122 T00001072
This is from the web. So from this I see the metar date in ASXP is out of date. So something must be wrong with their server.
