On which date did this issue happen?I mentioned Central Time because that's the time stamp used by my broker.
FYI: on last Sunday (Saturday to Sunday) the US switched from Eastern Standard Time (EST) to Eastern Daylight Saving Time (EDT).
Your country (according to your profile) is Singapore, and according to the information on the Web, your country does not use any daylight saving.
So, daylight saving switching in the US could indeed be the cause for this issue,
ie. maybe you did it during RMH while you believed it was pre-market.
You should tell the whole story with date.

Singapore Exchange Timezone
The Singapore Exchange uses the Asia/Singapore timezone. Commonly referred to as Singapore Standard Time. This timezone is currently GMT+08:00. The abbreviation for this timezone is +08.
The Asia/Singapore timezone does not observe Daylight Saving Time.
As can be seen: the current time difference is 12h, but in your recent posting you said even 14h to the Central Time in the US (meaning 13h to New York)...
