The following code snippet will output a date with a format like this pattern:
MM/DD/YYYY HH:MM (AM/PM)
For example:
5/31/2023 1:15 PM
Use the following snippet and just change the line for:
<mvt:assign name="l.settings:date:time_t" value="ternary(g.time_t GT 0, int(g.time_t), s.time_t)" />
to match your timestamp use-case. For Example:
<mvt:assign name="l.settings:date:time_t" value="l.settings:order:orderdate" />
