i cant seem to set a specific time when setting a reminder
There are two types of reminders:
1. Relative - those require the task to have a time and can be set to "10 minutes before", "1 hour before" etc.
2. Absolute - those don't require the task to have a date and time and for these you can set a date and time such as "today @ 2pm" or "every Friday at 13:20".
If you are using an absolute reminder and it doesn't work, please describe in detail how does it not work exactly? You set a time and it sets the wrong time? Does it show "invalid date"? Are you setting it up through the reminder menu or by typing <remind today at 2pm> within the task's name?
